Hi,
One of our satellites/checker got updated to 2.11 and our master is at 2.5.4. The cluster upgrade is on the horizon but want to fix the satellite until then.
My plan —
Take backup of /etc/icinga2 and /var/lib/icinga
Remove the 2.11 pkgs
Install 2.5.4 pkgs
Copy the cert (/var/lib/icinga2/cert) from backup
Start Icinga
Am I right? Please advise.
Thanks
