+# localizeStatus Migration
+
+Migrate your existing version data to support per-locale draft/published status when enabling `localizeStatus: true`.
+
+**Supported databases**: PostgreSQL, SQLite, MongoDB
+
+## Quick Start
+
+### 1. Create a migration file
+
+```bash
+payload migrate:create localize_status
+```
+
+### 2. Add the migration code
+
+**PostgreSQL / SQLite:**
+
+```typescript
+import type { MigrateDownArgs, MigrateUpArgs } from '@payloadcms/db-postgres'
+import { sql } from '@payloadcms/db-postgres'
+import { localizeStatus } from 'payload/migrations'
+
+export async function up({ db, payload }: MigrateUpArgs): Promise<void> {
+  await localizeStatus.up({
+    collectionSlug: 'posts', // 👈 Change to your collection
+    db,
+    payload,
+    sql,
+  })
+}
+
+export async function down({ db, payload }: MigrateDownArgs): Promise<void> {
+  await localizeStatus.down({
+    collectionSlug: 'posts',
+    db,
+    payload,
+    sql,
+  })
+}
+```
+
+**MongoDB:**
+
+```typescript
+import type { MigrateDownArgs, MigrateUpArgs } from '@payloadcms/db-mongodb'
+import { localizeStatus } from 'payload/migrations'
+
+export async function up({ payload }: MigrateUpArgs): Promise<void> {
+  await localizeStatus.up({
+    collectionSlug: 'posts', // 👈 Change to your collection
+    payload,
+  })
+}
+
+export async function down({ payload }: MigrateDownArgs): Promise<void> {
+  await localizeStatus.down({
+    collectionSlug: 'posts',
+    payload,
+  })
+}
+```
+
+**For globals**, use `globalSlug` instead:
+
+```typescript
+await localizeStatus.up({
+  globalSlug: 'settings', // 👈 Your global slug
+  payload,
+})
+```
+
+### 3. Run the migration
+
+```bash
+payload migrate
+```
+
+## What it does
+
+### BEFORE (old schema)
+
+- **One status for all locales**: When you publish, ALL locales are published
+- No way to have draft content in one locale while another is published
+
+### AFTER (new schema)
+
+- **Per-locale status**: Each locale can be draft or published independently
+- Full control over which locales are published at any time
+
+## Migration behavior
+
+The migration processes your version history chronologically to determine the correct status for each locale:
+
+1. **Published with specific locale** (`publishedLocale: 'en'`)
+
+   - That locale becomes 'published'
+   - Other locales remain 'draft'
+
+2. **Published without locale** (all locales)
+
+   - All locales become 'published'
+
+3. **Draft save**
+   - All locales become 'draft' (unpublish everything)
+
+### Example
+
+Version history:
+
+1. V1: Publish all → `{ en: 'published', es: 'published', de: 'published' }`
+2. V2: Draft save → `{ en: 'draft', es: 'draft', de: 'draft' }`
+3. V3: Publish EN only → `{ en: 'published', es: 'draft', de: 'draft' }`
+
+## When to use this
+
+Use this migration when:
+
+1. ✅ You have existing collections with `versions.drafts` enabled
+2. ✅ You want to enable `versions.drafts.localizeStatus: true`
+3. ✅ You need to preserve existing version history
+
+Don't use this if:
+
+- Starting a fresh project (just enable `localizeStatus: true` from the start)
+- Collection doesn't have versions enabled
+- Collection isn't localized
+
+## Safety
+
+### ⚠️ BACKUP YOUR DATABASE FIRST
+
+This migration modifies your database schema:
+
+- **PostgreSQL/SQLite**: Drops `version__status` column, adds `_status` to locales table
+- **MongoDB**: Transforms `version._status` from string to object
+- **Preserves**: `published_locale` column (needed for rollback)
+
+**Create a backup before running:**
+
+```bash
+# PostgreSQL
+pg_dump your_database > backup_before_migration.sql
+
+# MongoDB
+mongodump --db your_database --out ./backup_before_migration
+```
+
+### Migration guarantees
+
+✅ **Idempotent**: Safe to run multiple times (skips if already migrated)
+✅ **Validated**: Checks schema before proceeding
+✅ **Chronological**: Processes versions oldest-first for accuracy
+✅ **Rollback**: Includes `down()` to revert changes
+
+## Enable localizeStatus in your config
+
+After migrating, enable the feature:
+
+```typescript
+// Before
+{
+  slug: 'posts',
+  versions: {
+    drafts: true,
+  },
+}
+
+// After
+{
+  slug: 'posts',
+  versions: {
+    drafts: {
+      localizeStatus: true,
+    },
+  },
+}
+```
+
+## Rollback
+
+To revert the migration:
+
+```bash
+payload migrate:down
+```
+
+**Note**: Rollback uses "ANY locale published = globally published" logic, so some granularity may be lost.
+
+## Troubleshooting
+
+### "version\_\_status column not found"
+
+**Cause**: Migration already run, or column doesn't exist.
+
+**Solution**: Check if already migrated. If yes, no action needed.
+
+### Migration completes but data looks wrong
+
+**Cause**: `publishedLocale` field may have been null in original data.
+
+**Solution**: Review version history in database. The migration respects what's recorded in your data.
+
+### Want to migrate multiple collections?
+
+Call the migration multiple times:
+
+```typescript
+export async function up({ db, payload }: MigrateUpArgs): Promise<void> {
+  await localizeStatus.up({ collectionSlug: 'posts', db, payload, sql })
+  await localizeStatus.up({ collectionSlug: 'articles', db, payload, sql })
+  await localizeStatus.up({ globalSlug: 'settings', db, payload, sql })
+}
+```
+
+## Pre-flight checklist
+
+Before running:
+
+- [ ] Database backup created
+- [ ] Tested on staging/development database
+- [ ] Verified version data looks correct
+- [ ] `localizeStatus: true` ready to enable in config
+- [ ] Reviewed expected behavior
+- [ ] Rollback plan ready
