Upgrade debian 10 to 11
Hello,
how to upgrade nodes and clustercontrol server from debian 10 to 11 (mariadb 10.4 to 10.5)?
i try with "apt upgrade & apt dist-upgrade" but i lose clustercontrol gui and i try with a node and problem with cmon authentication. I can't buy licenses, it's too expensive for me.
Thank you very much for your help

Hi,
Upgrading OS is out of the scope of our product support. You may refer to the operating system's vendor or many other online resources about steps to upgrade to Debian 11. After upgrading to 11, you need to upgrade the package for MariaDB 10.4 to the "bullseye" package first, then you upgrade to MariaDB 10.5 "bullseye manually since ClusterControl does not support automatic upgrades between major DB versions.
Since the ClusterControl issue is related to an OS upgrade (there could be hundreds of dependencies issues), I believe the easiest way to solve this is to install a new ClusterControl on Debian 11 and re-import the DB cluster to the new ClusterControl server.
