+### Automatic Application
+
+SQL migrations in `server/database/migrations/*.sql` now automatically apply when you:
+- Start the development server (`npx nuxt dev` or [`npx nuxt dev --remote`](/docs/getting-started/remote-storage))
+- Preview builds locally ([`npx nuxthub preview`](/changelog/nuxthub-preview))
+- Deploy via [`npx nuxthub deploy`](/docs/getting-started/deploy#nuxthub-cli) or [Cloudflare Pages CI](/docs/getting-started/deploy#cloudflare-pages-ci)
+
+::tip
+All applied migrations are tracked in the `_hub_migrations` database table.
+::
+
+### Creating Migrations
+
+Generate a new migration file using:
+
+```bash [Terminal]
+npx nuxthub database migrations create <name>
 ```
 
-::callout
-Read more on [Cloudflare D1 documentation](https://developers.cloudflare.com/d1/build-databases/query-databases/).
+::important
+Migration names must only contain alphanumeric characters and `-` (spaces are converted to `-`).
 ::
+
+Migration files are created in `server/database/migrations/`.
+
+```bash [Example]
+> npx nuxthub database migrations create create-todos
+✔ Created ./server/database/migrations/0001_create-todos.sql
+```
+
+After creation, add your SQL queries to modify the database schema.
+
+
+::note{to="/docs/recipes/drizzle#npm-run-dbgenerate"}
+With [Drizzle ORM](/docs/recipes/drizzle), migrations are automatically created when you run `npx drizzle-kit generate`.
+::
+
+### Checking Migration Status
+
+View pending and applied migrations across environments:
+
+```bash [Terminal]
+# Local environment status
+npx nuxthub database migrations list
+
+# Preview environment status
+npx nuxthub database migrations list --preview
+
+# Production environment status
+npx nuxthub database migrations list --production
+```
+
+```bash [Example output]
+> npx nuxthub database migrations list --production
+ℹ Connected to project atidone.
+ℹ Using https://todos.nuxt.dev to retrieve migrations.
+✔ Found 1 migration on atidone...

+🕒 ./server/database/migrations/0002_create-users.sql Pending
+```
+
+### Marking Migrations as Applied
+
+For databases with existing migrations, prevent NuxtHub from rerunning them by marking them as applied:
+
+```bash [Terminal]
+# Mark applied in local environment
+npx nuxthub database migrations mark-all-applied
+
+# Mark applied in preview environment
+npx nuxthub database migrations mark-all-applied --preview
+
+# Mark applied in production environment
+npx nuxthub database migrations mark-all-applied --production
+```
+
+::collapsible{name="self-hosting docs"}
+When [self-hosting](/docs/getting-started/deploy#self-hosted), set these environment variables before running commands: :br :br
+
+```bash [Terminal]
+NUXT_HUB_PROJECT_URL=<url> NUXT_HUB_PROJECT_SECRET_KEY=<secret> nuxthub database migrations mark-all-applied
+```
+::
+
+### Migrating from Drizzle ORM
+
+Since NuxtHub doesn't recognize previously applied Drizzle ORM migrations (stored in `__drizzle_migrations`), it will attempt to rerun all migrations in `server/database/migrations/*.sql`. To prevent this:
+
+1. Mark existing migrations as applied in each environment:
+
+    ```bash [Terminal]
+    # Local environment
+    npx nuxthub database migrations mark-all-applied
+
+    # Preview environment
+    npx nuxthub database migrations mark-all-applied --preview
+
+    # Production environment
+    npx nuxthub database migrations mark-all-applied --production
+    ```
+
+2. Remove `server/plugins/database.ts` as it's no longer needed.
