## D1 migrations support nested layouts via \`migrations\_pattern\`

May 29, 2026 

[ D1 ](https://developers.cloudflare.com/d1/) 

You can now point `wrangler d1 migrations apply` at a nested migrations layout — such as the one produced by [Drizzle ↗](https://orm.drizzle.team/) (`migrations/0001_init/migration.sql`) — using the new `migrations_pattern` D1 binding config:

JSONC

```
{  "d1_databases": [    {      "binding": "DB",      "database_name": "my-database",      "database_id": "<UUID>",      "migrations_dir": "migrations",      "migrations_pattern": "migrations/*/migration.sql",    },  ],}
```

`migrations_pattern` is a glob (relative to your Wrangler config file) used to discover migration files. It defaults to `${migrations_dir}/*.sql`, so existing projects keep working unchanged. Each migration's name is recorded in the migrations table as a path relative to `migrations_dir`.
