Upgrade process
As always: Replace the executables (via the installers) and the database of the server/client will be updated on first running it.
Place the files from the update directory into C:\Program Files\UrBackupServer\urbackup or /var/urbackup to auto-update clients. Disable Download client from update server in the server settings to prevent the server from downloading the current version.
On Linux e.g. with this update script: https://github.com/ptempier/get_urbackupclient/blob/master/updateclient.sh
Downgrade process (server)
Stop the UrBackup server, restore C:\Program Files\UrBackupServer\urbackup or /var/urbackup from a backup before upgrade and then install the previous version over the beta release.
