  1. In your service, in the Backups section, click Backup management.
  2. Click Fork & restore.
  3. Choose the backup to fork from.
  4. Enter a name, and select the cloud and plan.
  5. Click Create fork.

Once the new service is running, change your application's connection settings to point to it and power off the original service.
