we have a 2 Icinga2 Master Cluster setup (+Galera DB Cluster) with multiple Satellite servers. The Master servers are deployed on two different sites.
One of these sites will be closed in the near future and we have to move the primary Icinga2 master to another site. So we have to change the IP address and also the FQDN because we have the sitename in the hostname.
I know I have to create a new certificate for the master. But what are the consequences? Do I have to change anything (besides the FQDN and IP address in the zones file) on the satellites or even on the agents?
