 - The migration list is an ordered array of tables, specified as a key in your Wrangler configuration file. You can define the migration for each environment, as well as at the top level.

+  - Top-level migration is specified at the top-level `migrations` key in the Wrangler configuration file.
+  - Environment-level migration is specified by a `migrations` key inside the `env` key of the Wrangler configuration file (`[env.<environment_name>.migrations]`).
+    - Example Wrangler file:
+    ```jsonc title="wrangler.jsonc"
+    {
+    // top-level default migrations
+    "migrations": [{ ... }],
+    "env": {
+    "staging": {

+  - Migrations at at the environment-level override migrations at the top level.
 
 - All migrations are applied at deployment. Each migration can only be applied once per [environment](/durable-objects/reference/environments/).

+You can define a Durable Object migration for each environment, as well as at the top level. Migrations at at the environment-level override migrations at the top level.

 ## Local development
 
 Local development sessions create a standalone, local-only environment that mirrors the production environment, so that you can test your Worker and Durable Objects before you deploy to production.
