Roll Back an Upgrade

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

Stop and remove the current Harbor service if it is still running.
```
cd harbor
docker-compose down
```
Remove current Harbor instance.
```
rm -rf harbor
```
Restore the older version package of Harbor.
```
mv /my_backup_dir/harbor harbor
```
Restore database, copy the data files from backup directory to you data volume, by default /data/database.
Restart Harbor service using the previous configuration.
If 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.
