Icinga2 upgrade assistance

Can you share best way to replace both of these Centos 7 master servers? I want to avoid jumping through all my Endpoints and ex. adding another master server (ex. master3) to zone there and do it that way.

Thanks for your post. Actually, there is currently another active thread with a very similar topic. Please take a look at https://community.icinga.com/t/i-need-to-upgrade-centos7-to-rhel-v9/13890.

Please don’t try to add another master node, as the master-master-replication only allows two nodes.

@subgenius

Also is all this CA inside the database or there is some guide how to move that to new server?

Please refer to the documentation’s backup section, as @log1c did in the mentioned thread above. The CA as well as other backup- or migration-worthy files should reside within /var/lib/icinga2.
