Fixes https://github.com/payloadcms/payload/issues/12263
This was caused by passing not needed columns to the `SELECT DISTINCT`
query, which we execute in case if we have a filter / sort by a nested
field / relationship. Since the only columns that we need to pass to the
`SELECT DISTINCT` query are: ID and field(s) specified in `sort`, we now
filter the `selectFields` variable.
Lexical tests comprise almost half of the collections in the fields
suite, and are starting to become complex to manage.
They are sometimes related to other auxiliary collections, so
refactoring one test sometimes breaks another, seemingly unrelated one.
In addition, the fields suite is very large, taking a long time to
compile. This will make it faster.
Some ideas for future refactorings:
- 3 main collections: defaultFeatures, fully featured, and legacy.
Legacy is the current one that has multiple editors and could later be
migrated to the first two.
- Avoid collections with more than 1 editor.
- Create reseed buttons to restore the editor to certain states, to
avoid a proliferation of collections and documents.
- Reduce the complexity of the three auxiliary collections (text, array,
upload), which are rarely or never used and have many fields designed
for tests in the fields suite.
The `localized` properly was not stripped out of referenced block fields, if any parent was localized. For normal fields, this is done in sanitizeConfig. As the same referenced block config can be used in both a localized and non-localized config, we are not able to strip it out inside sanitizeConfig by modifying the block config.
Instead, this PR had to bring back tedious logic to handle it everywhere the `field.localized` property is accessed. For backwards-compatibility, we need to keep the existing sanitizeConfig logic. In 4.0, we should remove it to benefit from better test coverage of runtime field.localized handling - for now, this is done for our test suite using the `PAYLOAD_DO_NOT_SANITIZE_LOCALIZED_PROPERTY` flag.
If you have multiple blocks that are used in multiple places, this can quickly blow up the size of your Payload Config. This will incur a performance hit, as more data is
1. sent to the client (=> bloated `ClientConfig` and large initial html) and
2. processed on the server (permissions are calculated every single time you navigate to a page - this iterates through all blocks you have defined, even if they're duplicative)
This can be optimized by defining your block **once** in your Payload Config, and just referencing the block slug whenever it's used, instead of passing the entire block config. To do this, the block can be defined in the `blocks` array of the Payload Config. The slug can then be passed to the `blockReferences` array in the Blocks Field - the `blocks` array has to be empty for compatibility reasons.
```ts
import { buildConfig } from 'payload'
import { lexicalEditor, BlocksFeature } from '@payloadcms/richtext-lexical'
// Payload Config
const config = buildConfig({
// Define the block once
blocks: [
{
slug: 'TextBlock',
fields: [
{
name: 'text',
type: 'text',
},
],
},
],
collections: [
{
slug: 'collection1',
fields: [
{
name: 'content',
type: 'blocks',
// Reference the block by slug
blockReferences: ['TextBlock'],
blocks: [], // Required to be empty, for compatibility reasons
},
],
},
{
slug: 'collection2',
fields: [
{
name: 'editor',
type: 'richText',
editor: lexicalEditor({
BlocksFeature({
// Same reference can be reused anywhere, even in the lexical editor, without incurred performance hit
blocks: ['TextBlock'],
})
})
},
],
},
],
})
```
## v4.0 Plans
In 4.0, we will remove the `blockReferences` property, and allow string block references to be passed directly to the blocks `property`. Essentially, we'd remove the `blocks` property and rename `blockReferences` to `blocks`.
The reason we opted to a new property in this PR is to avoid breaking changes. Allowing strings to be passed to the `blocks` property will prevent plugins that iterate through fields / blocks from compiling.
## PR Changes
- Testing: This PR introduces a plugin that automatically converts blocks to block references. This is done in the fields__blocks test suite, to run our existing test suite using block references.
- Block References support: Most changes are similar. Everywhere we iterate through blocks, we have to now do the following:
1. Check if `field.blockReferences` is provided. If so, only iterate through that.
2. Check if the block is an object (= actual block), or string
3. If it's a string, pull the actual block from the Payload Config or from `payload.blocks`.
The exception is config sanitization and block type generations. This PR optimizes them so that each block is only handled once, instead of every time the block is referenced.
## Benchmarks
60 Block fields, each block field having the same 600 Blocks.

## Future Plans
1. This PR does not yet deduplicate block references during permissions calculation. We'll optimize that in a separate PR, as this one is already large enough
2. The same optimization can be done to deduplicate fields. One common use-case would be link field groups that may be referenced in multiple entities, outside of blocks. We might explore adding a new `fieldReferences` property, that allows you to reference those same `config.blocks`.
Fixes https://github.com/payloadcms/payload/issues/10780
Previously, with enabled versions, nested select `hasMany: true` fields
weren't working with SQL database adapters. This was due to wrongly
passed `parent` to select rows data because we store arrays and blocks
in versions a bit differently, using both, `id` and `_uuid` (which
contains the normal Object ID) columns. And unlike with non versions
`_uuid` column isn't actually applicable here as it's not unique, thus
we need to save blocks/arrays first and then map their ObjectIDs to
generated by the database IDs and use them for select fields `parent`
data
Field paths within hooks are not correct.
For example, an unnamed tab containing a group field and nested text
field should have the path:
- `myGroupField.myTextField`
However, within hooks that path is formatted as:
- `_index-1.myGroupField.myTextField`
The leading index shown above should not exist, as this field is
considered top-level since it is located within an unnamed tab.
This discrepancy is only evident through the APIs themselves, such as
when creating a request with invalid data and reading the validation
errors in the response. Form state contains proper field paths, which is
ultimately why this issue was never caught. This is because within the
admin panel we merge the API response with the current form state,
obscuring the underlying issue. This becomes especially obvious in
#10580, where we no longer initialize validation errors within form
state until the form has been submitted, and instead rely solely on the
API response for the initial error state.
Here's comprehensive example of how field paths _should_ be formatted:
```
{
// ...
fields: [
{
// path: 'topLevelNamedField'
// schemaPath: 'topLevelNamedField'
// indexPath: ''
name: 'topLevelNamedField',
type: 'text',

],
},
]
}
```
### What?
Previously, field error messages displayed in toast notifications used
the field path to reference fields that failed validation. This
path-based approach was necessary to distinguish between fields that
might share the same name when nested inside arrays, groups, rows, or
collapsible fields.
However, the human readability of these paths was lacking, especially
for unnamed fields like rows and collapsible fields. For example:
- A text field inside a row could display as: `_index-0.text`
- A text field nested within multiple arrays could display as:
`items.0.subArray.0.text`
These outputs are technically correct but not user-friendly.
### Why?
While the previous format was helpful for pinpointing the specific field
that caused the validation error, it could be more user-friendly and
clearer to read. The goal is to maintain the same level of accuracy
while improving the readability for both developers and content editors.
### How?
To improve readability, the following changes were made:
1. Use Field Labels Instead of Field Paths:
- The ValidationError component now uses the label prop from the field
config (if available) instead of the field’s name.
- If a label is provided, it will be used in the error message.
- If no label exists, it will fall back to the field’s name.
2. Remove _index from Paths for Unnamed Fields (In the validationError
component only):
- For unnamed fields like rows and collapsibles, the _index prefix is
now stripped from the output to make it cleaner.
- Instead of `_index-0.text`, it now outputs just `Text`.
3. Reformat the Error Path for Readability:
- The error message format has been improved to be more human-readable,
showing the field hierarchy in a structured way with array indices
converted to 1-based numbers.
#### Example transformation:
##### Before:
The following fields are invalid: `items.0.subArray.0.text`
##### After:
The following fields are invalid: `Items 1 > SubArray 1 > Text`
IDs that are supplied directly through the API, such as client-side
generated IDs when adding new blocks and array rows, are overwritten on
create. This is because when adding blocks or array rows on the client,
their IDs are generated first before being sent to the server for
processing. Then when the server receives this data, it incorrectly
overrides them to ensure they are unique when using relational DBs. But
this only needs to happen when no ID was supplied on create, or
specifically when duplicating documents via the `beforeDuplicate` hook.
### What?
Querying by nested to rows fields in has many relationships like this:
```ts
const result = await payload.find({
collection: 'relationship-fields',
where: {
'relationToRowMany.title': { equals: 'some-title' },
},
})
```
Where the related collection:
```ts
const RowFields: CollectionConfig = {
slug: rowFieldsSlug,
fields: [
{
type: 'row',
fields: [
{
name: 'title',
label: 'Title within a row',
type: 'text',
required: true,
},
],
},
],
}
```
was broken
### Why?
We migrated to use `flattenedFields`, but not in this specific case.
This error would be caught earlier we used `noImplictAny` typescript
rule. https://www.typescriptlang.org/tsconfig/#noImplicitAny which
wouldn't allow us to create variable like this:
```ts
let relationshipFields // relationshipFields is any here
```
Instead, we should write:
```ts
let relationshipFields: FlattenedField[]
```
We should migrate to it and `strictNullChecks` as well.
Fixes https://github.com/payloadcms/payload/issues/9534
Rework of https://github.com/payloadcms/payload/pull/5912
### What?
Now, when `defaultValue` is defined as function you can receive the
`req` argument:
```ts
{
name: 'defaultValueFromReq',
type: 'text',
defaultValue: async ({ req, user, locale }) => {
return Promise.resolve(req.context.defaultValue)
},
},
```
`user` and `locale` even though are repeated in `req`, this potentially
leaves some room to add more args in the future without removing them
now.
This also improves type for `defaultValue`:
```ts
type SerializableValue = boolean | number | object | string
export type DefaultValue =
| ((args: {
locale?: TypedLocale
req: PayloadRequest
user: PayloadRequest['user']
}) => SerializableValue)
| SerializableValue
```
### Why?
To access the current URL / search params / Local API and other things
directly in `defaultValue`.
### How?
Passes `req` through everywhere where we call `defaultValue()`
### What?
Previously, using Postgres, select fields with `hasMany: true` weren't
clearable.
Meaning, you couldn't pass an empty array:
```ts
const updatedDoc = await payload.update({
id,
collection: 'select-fields',
data: {
selectHasMany: [],
},
})
```
### Why?
To achieve the same behavior with MongoDB.
### How?
Modifies logic in `packages/drizzle/src/upsertRow/index.ts` to include
empty arrays.
Deprecates `getPayloadHMR` and simplifies this pattern into a single
`import { getPayload } from 'payload'`.
We will still retain the exported `getPayloadHMR` but it now will throw
a deprecation warning with instructions for how to migrate.
Currently, Payload renders all custom components on initial compile of
the admin panel. This is problematic for two key reasons:
1. Custom components do not receive contextual data, i.e. fields do not
receive their field data, edit views do not receive their document data,
etc.
2. Components are unnecessarily rendered before they are used
This was initially required to support React Server Components within
the Payload Admin Panel for two key reasons:
1. Fields can be dynamically rendered within arrays, blocks, etc.
2. Documents can be recursively rendered within a "drawer" UI, i.e.
relationship fields
3. Payload supports server/client component composition
In order to achieve this, components need to be rendered on the server
and passed as "slots" to the client. Currently, the pattern for this is
to render custom server components in the "client config". Then when a
view or field is needed to be rendered, we first check the client config
for a "pre-rendered" component, otherwise render our client-side
fallback component.
But for the reasons listed above, this pattern doesn't exactly make
custom server components very useful within the Payload Admin Panel,
which is where this PR comes in. Now, instead of pre-rendering all
components on initial compile, we're able to render custom components
_on demand_, only as they are needed.
To achieve this, we've established [this
pattern](https://github.com/payloadcms/payload/pull/8481) of React
Server Functions in the Payload Admin Panel. With Server Functions, we
can iterate the Payload Config and return JSX through React's
`text/x-component` content-type. This means we're able to pass
contextual props to custom components, such as data for fields and
views.
## Breaking Changes
1. Add the following to your root layout file, typically located at
`(app)/(payload)/layout.tsx`:
```diff
/* THIS FILE WAS GENERATED AUTOMATICALLY BY PAYLOAD. */
/* DO NOT MODIFY IT BECAUSE IT COULD BE REWRITTEN AT ANY TIME. */
+ import type { ServerFunctionClient } from 'payload'
import config from '@payload-config'
import { RootLayout } from '@payloadcms/next/layouts'
import { handleServerFunctions } from '@payloadcms/next/utilities'
import React from 'react'
import { importMap } from './admin/importMap.js'
import './custom.scss'
type Args = {
children: React.ReactNode
}
+ const serverFunctions: ServerFunctionClient = async function (args) {
+ 'use server'
+ return handleServerFunctions({
+ ...args,
+ config,
+ importMap,
+ })
+ }
const Layout = ({ children }: Args) => (
<RootLayout
config={config}
importMap={importMap}
+ serverFunctions={serverFunctions}
>
{children}
</RootLayout>
)
export default Layout
```
2. If you were previously posting to the `/api/form-state` endpoint, it
no longer exists. Instead, you'll need to invoke the `form-state` Server
Function, which can be done through the _new_ `getFormState` utility:
```diff
- import { getFormState } from '@payloadcms/ui'
- const { state } = await getFormState({
- apiRoute: '',
- body: {
- // ...
- },
- serverURL: ''
- })
+ const { getFormState } = useServerFunctions()
+
+ const { state } = await getFormState({
+ // ...
+ })
```
## Breaking Changes
```diff
- useFieldProps()
- useCellProps()
```
More details coming soon.

### What?
Adds full support for the point field to Postgres and Vercel Postgres
adapters through the Postgis extension. Fully the same API as with
MongoDB, including support for `near`, `within` and `intersects`
operators.
Additionally, exposes to adapter args:
*
`tablesFilter`https://orm.drizzle.team/docs/drizzle-kit-push#including-tables-schemas-and-extensions.
* `extensions` list of extensions to create, for example `['vector',
'pg_search']`, `postgis` is created automatically if there's any point
field
### Why?
It's essential to support that field type, especially if the postgres
adapter should be out of beta on 3.0 stable.
### How?
* Bumps `drizzle-orm` to `0.36.1` and `drizzle-kit` to `0.28.0` as we
need this change https://github.com/drizzle-team/drizzle-orm/pull/3141
* Uses its functions to achieve querying functionality, for example the
`near` operator works through `ST_DWithin` or `intersects` through
`ST_Intersects`.
* Removes MongoDB condition from all point field tests, but keeps for
SQLite

This noticeably improves performance in the admin panel, for example
when there are multiple richtext editors on one page (& likely
performance in other areas too, though I mainly tested rich text).
The babel plugin currently only optimizes files with a 'use client'
directive at the top - thus we have to make sure to add use client
wherever possible, even if it's imported by a parent client component.
There's one single component that broke when it was compiled using the
React compiler (it stopped being reactive and failed one of our admin
e2e tests):
150808f608
opting out of it completely fixed that issue
Fixes https://github.com/payloadcms/payload/issues/7366
This PR makes three major changes to the codebase:
1. [Component Paths](#component-paths)
Instead of importing custom components into your config directly, they
are now defined as file paths and rendered only when needed. That way
the Payload config will be significantly more lightweight, and ensures
that the Payload config is 100% server-only and Node-safe. Related
discussion: https://github.com/payloadcms/payload/discussions/6938
2. [Client Config](#client-config)
Deprecates the component map by merging its logic into the client
config. The main goal of this change is for performance and
simplification. There was no need to deeply iterate over the Payload
config twice, once for the component map, and another for the client
config. Instead, we can do everything in the client config one time.
This has also dramatically simplified the client side prop drilling
through the UI library. Now, all components can share the same client
config which matches the exact shape of their Payload config (with the
exception of non-serializable props and mapped custom components).
3. [Custom client component are no longer
server-rendered](#custom-client-components-are-no-longer-server-rendered)
Previously, custom components would be server-rendered, no matter if
they are server or client components. Now, only server components are
rendered on the server. Client components are automatically detected,
and simply get passed through as `MappedComponent` to be rendered fully
client-side.
## Component Paths
Instead of importing custom components into your config directly, they
are now defined as file paths and rendered only when needed. That way
the Payload config will be significantly more lightweight, and ensures
that the Payload config is 100% server-only and Node-safe. Related
discussion: https://github.com/payloadcms/payload/discussions/6938
In order to reference any custom components in the Payload config, you
now have to specify a string path to the component instead of importing
it.
Old:
```ts
import { MyComponent2} from './MyComponent2.js'
admin: {
components: {
Label: MyComponent2
},
},
```
New:
```ts
admin: {
components: {
Label: '/collections/Posts/MyComponent2.js#MyComponent2', // <= has to be a relative path based on a baseDir configured in the Payload config - NOT relative based on the importing file
},
},
```
### Local API within Next.js routes
Previously, if you used the Payload Local API within Next.js pages, all
the client-side modules are being added to the bundle for that specific
page, even if you only need server-side functionality.
This `/test` route, which uses the Payload local API, was previously 460
kb. It is now down to 91 kb and does not bundle the Payload client-side
admin panel anymore.
All tests done
[here](https://github.com/payloadcms/payload-3.0-demo/tree/feat/path-test)
with beta.67/PR, db-mongodb and default richtext-lexical:
**dev /admin before:**

**dev /admin after:**

---
**dev /test before:**

**dev /test after:**

---
**build before:**

**build after::**

### Usage of the Payload Local API / config outside of Next.js
This will make it a lot easier to use the Payload config / local API in
other, server-side contexts. Previously, you might encounter errors due
to client files (like .scss files) not being allowed to be imported.
## Client Config
Deprecates the component map by merging its logic into the client
config. The main goal of this change is for performance and
simplification. There was no need to deeply iterate over the Payload
config twice, once for the component map, and another for the client
config. Instead, we can do everything in the client config one time.
This has also dramatically simplified the client side prop drilling
through the UI library. Now, all components can share the same client
config which matches the exact shape of their Payload config (with the
exception of non-serializable props and mapped custom components).
This is breaking change. The `useComponentMap` hook no longer exists,
and most component props have changed (for the better):
```ts
const { componentMap } = useComponentMap() // old
const { config } = useConfig() // new
```
The `useConfig` hook has also changed in shape, `config` is now a
property _within_ the context obj:
```ts
const config = useConfig() // old

## Custom Client Components are no longer server rendered
Previously, custom components would be server-rendered, no matter if
they are server or client components. Now, only server components are
rendered on the server. Client components are automatically detected,
and simply get passed through as `MappedComponent` to be rendered fully
client-side.
The benefit of this change:
Custom client components can now receive props. Previously, the only way
for them to receive dynamic props from a parent client component was to
use hooks, e.g. `useFieldProps()`. Now, we do have the option of passing
in props to the custom components directly, if they are client
components. This will be simpler than having to look for the correct
hook.
This makes rendering them on the client a little bit more complex, as
you now have to check if that component is a server component (=>
already has been rendered) or a client component (=> not rendered yet,
has to be rendered here). However, this added complexity has been
alleviated through the easy-to-use `<RenderMappedComponent />` helper.
This helper now also handles rendering arrays of custom components (e.g.
beforeList, beforeLogin ...), which actually makes rendering custom
components easier in some cases.
## Misc improvements
This PR includes misc, breaking changes. For example, we previously
allowed unions between components and config object for the same
property. E.g. for the custom view property, you were allowed to pass in
a custom component or an object with other properties, alongside a
custom component.
Those union types are now gone. You can now either pass an object, or a
component. The previous `{ View: MyViewComponent}` is now `{ View: {
Component: MyViewComponent} }` or `{ View: { Default: { Component:
MyViewComponent} } }`.
This dramatically simplifies the way we read & process those properties,
especially in buildComponentMap. We can now simply check for the
existence of one specific property, which always has to be a component,
instead of running cursed runtime checks on a shared union property
which could contain a component, but could also contain functions or
objects.

## Description
Prior to this change, the `defaultValue` for fields have only been used
in the application layer of Payload. With this change, you get the added
benefit of having the database columns get the default also. This is
especially helpful when adding new columns to postgres with existing
data to avoid needing to write complex migrations. In MongoDB this
change applies the default to the Mongoose model which is useful when
calling payload.db.create() directly.
This only works for statically defined values.

Allows empty strings ('') as defaultValue for fields of types: 'text'; 'textarea'; 'email'; 'code'. This can be useful when you want to ensure the value is always a string instead of null/undefined.
# Breaking Changes
### New file import locations
Exports from the `payload` package have been _significantly_ cleaned up.
Now, just about everything is able to be imported from `payload`
directly, rather than an assortment of subpath exports. This means that
things like `import { buildConfig } from 'payload/config'` are now just
imported via `import { buildConfig } from 'payload'`. The mental model
is significantly simpler for developers, but you might need to update
some of your imports.
Payload now exposes only three exports:
1. `payload` - all types and server-only Payload code
2. `payload/shared` - utilities that can be used in either the browser
or in Node environments
3. `payload/node` - heavy utilities that should only be imported in Node
scripts and never be imported into bundled code like Next.js
### UI library pre-bundling
With this release, we've dramatically sped up the compile time for
Payload by pre-bundling our entire UI package for use inside of the
Payload admin itself. There are new exports that should be used within
Payload custom components:
1. `@payloadcms/ui/client` - all client components
2. `@payloadcms/ui/server` - all server components
For all of your custom Payload admin UI components, you should be
importing from one of these two pre-compiled barrel files rather than
importing from the more deeply nested exports directly. That will keep
compile times nice and speedy, and will also make sure that the bundled
JS for your admin UI is kept small.
For example, whereas before, if you imported the Payload `Button`, you
would have imported it like this:
```ts
import { Button } from '@payloadcms/ui/elements/Button'
```
Now, you would import it like this:
```ts
import { Button } from '@payloadcms/ui/client'
```
This is a significant DX / performance optimization that we're pretty
pumped about.
However, if you are importing or re-using Payload UI components
_outside_ of the Payload admin UI, for example in your own frontend
apps, you can import from the individual component exports which will
make sure that the bundled JS is kept to a minimum in your frontend
apps. So in your own frontend, you can continue to import directly to
the components that you want to consume rather than importing from the
pre-compiled barrel files.
Individual component exports will now come with their corresponding CSS
and everything will work perfectly as-expected.
### Specific exports have changed
- `'@payloadcms/ui/templates/Default'` and
`'@payloadcms/ui/templates/Minimal`' are now exported from
`'@payloadcms/next/templates'`
- Old: `import { LogOut } from '@payloadcms/ui/icons/LogOut'` new:
`import { LogOutIcon } from '@payloadcms/ui/icons/LogOut'`
## Background info
In effort to make local dev as fast as possible, we need to import as
few files as possible so that the compiler has less to process. One way
we've achieved this in the Admin Panel was to _remove_ all .scss imports
from all components in the `@payloadcms/ui` module using a build
process. This stripped all `import './index.scss'` statements out of
each component before injecting them into `dist`. Instead, it bundles
all of the CSS into a single `main.css` file, and we import _that_ at
the root of the app.
While this concept is _still_ the right solution to the problem, this
particular approach is not viable when using these components outside
the Admin Panel, where not only does this root stylesheet not exist, but
where it would also bloat your app with unused styles. Instead, we need
to _keep_ these .scss imports in place so they are imported directly
alongside your components, as expected. Then, we need create a _new_
build step that _separately_ compiles the components _without_ their
stylesheets—this way your app can consume either as needed from the new
`client` and `server` barrel files within `@payloadcms/ui`, i.e. from
within `@payloadcms/next` and all other admin-specific packages and
plugins.
This way, all other applications will simply import using the direct
file paths, just as they did before. Except now they come with
stylesheets.
And we've gotten a pretty awesome initial compilation performance boost.

BREAKING CHANGE:
Moves `upload` field and `relationship` fields with `hasMany: false` &
`relationTo: string` from the many-to-many `_rels` join table to simple
columns. This only affects Postgres database users.
## TL;DR
We have dramatically simplified the storage of simple relationships in
relational databases to boost performance and align with more expected
relational paradigms. If you are using the beta Postgres adapter, and
you need to keep simple relationship data, you'll need to run a
migration script that we provide you.
### Background
For example, prior to this update, a collection of "posts" with a simple
`hasMany: false` and `relationTo: 'categories'` field would have a
`posts_rels` table where the category relations would be stored.
This was somewhat unnecessary as simple relations like this can be
expressed with a `category_id` column which is configured as a foreign
key. This also introduced added complexity for dealing directly with the
database if all you have are simple relations.
### Who needs to migrate
You need to migrate if you are using the beta Postgres database adapter
and any of the following applies to you.
- If you have versions enabled on any collection / global
- If you use the `upload` field
- If you have relationship fields that are `hasMany: false` (default)
and `relationTo` to a single category ([has
one](https://payloadcms.com/docs/fields/relationship#has-one)) relations
### We have a migration for you
Even though the Postgres adapter is in beta, we've prepared a predefined
migration that will work out of the box for you to migrate from an
earlier version of the adapter to the most recent version easily.
It makes the schema changes in step with actually moving the data from
the old locations to the new before adding any null constraints and
dropping the old columns and tables.
### How to migrate
The steps to preserve your data while making this update are as follows.
These steps are the same whether you are moving from Payload v2 to v3 or
a previous version of v3 beta to the most recent v3 beta.
**Important: during these steps, don't start the dev server unless you
have `push: false` set on your Postgres adapter.**
#### Step 1 - backup
Always back up your database before performing big changes, especially
in production cases.
#### Step 2 - create a pre-update migration
Before updating to new Payload and Postgres adapter versions, run
`payload migrate:create` without any other config changes to have a
prior snapshot of the schema from the previous adapter version
#### Step 3 - if you're migrating a dev DB, delete the dev `push` row
from your `payload_migrations` table
If you're migrating a dev database where you have the default setting to
push database changes directly to your DB, and you need to preserve data
in your development database, then you need to delete a `dev` migration
record from your database.
Connect directly to your database in any tool you'd like and delete the
dev push record from the `payload_migrations` table using the following
SQL statement:
```sql
DELETE FROM payload_migrations where batch = -1`
```
#### Step 4 - update Payload and Postgres versions to most recent
Update packages, making sure you have matching versions across all
`@payloadcms/*` and `payload` packages (including
`@payloadcms/db-postgres`)
#### Step 5 - create the predefined migration
Run the following command to create the predefined migration we've
provided:
```
payload migrate:create --file @payloadcms/db-postgres/relationships-v2-v3
```
#### Step 6 - migrate!
Run migrations with the following command:
```
payload migrate
```
Assuming the migration worked, you can proceed to commit this change and
distribute it to be run on all other environments.
Note that if two servers connect to the same database, only one should
be running migrations to avoid transaction conflicts.
