Upgrade
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:
cd /var/urbackup && wget -r -l1 --no-parent --reject "index.html*" -nH -nd -N "https://ssl.webpack.de/beta.urbackup.org/Client/2.1.3%20beta/update/"Another option :

Downgrade (server)
Stop the UrBackup server, restore C:\Program Files\UrBackupServer\urbackup or /var/urbackupfrom a backup before upgrade and then install the previous version over the beta release.
