+# Rollback A Specific Migration Out Of Order
+
+If you want to rollback the latest migration that is `up`, you can use:
+
+```bash
+$ rails db:rollback
+```
+
+It deals explicitly with the latest `up` migration and nothing else. Even if
+you name a specific `VERSION`, it will still just rollback the one latest.
+
+Instead, if you want to target a specific past migration for rollback, you'll
+want the `db:migrate:down` command. You'll need to specify the version, which
+is the timestamp number in the filename of the migration.
+
+Here is what this looks like for a recent migration I had to rollback.
+
+```bash
+$ rails db:migrate:down VERSION=20210302171858
+```
