Roll Back from an Upgrade	45

If, for any reason, you need to roll back to the previous version of Harbor, perform the following steps.

{{< note >}} To roll back from an upgrade, you must have backed up the previous version of Harbor. For information about backing up Harbor before an upgrade, see Upgrade Harbor and Migrate Data. {{< /note >}}

1. Stop and remove the current Harbor service if it is still running.

   cd harbor
   docker-compose down
   

2. Remove current Harbor instance.

   rm -rf harbor
   

3. Restore the older version of Harbor.

   mv /my_backup_dir/harbor harbor
   

4. To restore the database, copy the data files from the backup directory to your data volume, which by default is /data/database.

5. Restart the Harbor service using the previous configuration.

   If the previous version of Harbor was installed by a release build:

   cd harbor
   ./install.sh
   

{{< note >}} While you can roll back an upgrade to the state before you started the upgrade, Harbor does not support downgrades. {{< /note >}}
