Dev databases are located in the same region as your app and cannot be migrated to another region. If you migrate your app to a different region, the app won’t be able to access the associated dev database anymore. If you need to migrate your app and dev database, we recommend either backing up the contents of the database and restoring it after the app’s migration, or using a DigitalOcean Managed Database instead. You can migrate managed databases independently of apps to different regions as needed.
