We have an icinga master node running in RHEL7. As RHEL7 is going to EOS, customer requests to upgrade the server to RHEL8. Any suggestions about how to proceed?

Icinga requires a paid subscription for RHEL8+ (and other Enterprise Linux)

Or you/the customer can think about an extended support contract for RHEL7.
So you (or the customer) will need to calculate, I guess.
I don’t know which would come cheaper.
Additionally one also could build the RHEL8 packages from source themselves, as Icinga is still opensource. The internet should provide docs on how to do something like that.
From the update perspective (very basic description):
- Update the existing install to the latest available version.
- do the RHEL8 update
- add new package sources for rhel8
- check for Icinga updates
Speaking as one who does this frequently on Ubuntu systems I can say that there are rarely problem on the Icinga-side with inplace-upgrade of the underlying system.
Thanks for the answer.
But regarding the upgrade steps, which files/folders do i need to backup first? We need to keep the icinga director, zones, etc.
Backup should at least be the
/etc/icinga2 folder, the
/var/lib/icinga2 folder and the respective databases of icinga2/icingaweb/icingadirector.
