has anyone upgraded the OS of his/her Icinga-Installation from Debian Stretch to Debian Buster? Did you run in any errors? Any additional tipps for preparation (aside from backups and a rollback-plan)?
I’m running the latest Icinga-Version with Icingaweb (running via nginx) and Icinga-Director in a 2-Node-Cluster.
Edit: Corrected Jessie to Stretch
