Migrate from old CentOS to Ubuntu

Icinga 2

Hi Community,
I’m not sure if I am right in this category because it can fit everywhere.
I have to masters and a whole bunch of satellites, and my masters are installed on an “old” CentOS 8 in Azure. Now I want to migrate from the CentOS Boxes to Ubuntu and I want to verify the way I want to go:

  1. Backup the Databases + /etc/icinga* + /usr/share/icingaweb2/* + /var/lib/icinga2* on both masters
  2. Install 2 new blank Ubuntu 22.04 LTS with icinga2 + icingaweb2 + modules VMs
  3. Remove one master from the HA
  4. Setup one Ubuntu and add it to the master zone, switch DNS entry
  5. Change icinga director Endpoint to the new installed machine
  6. Remove second CentOS master from the HA
  7. Setup second Ubuntu and join HA
  8. Hope that everything is fine

Did I forget some steps? Has someone done this before?

Thank you very much
Stephan

Sounds good. I would do the config master last.

Hi, is there any news on this topic? Did the migration plan work? Are there any suggestions?

I don’t see Director on the list, and I assume it is not included in the instructions from above, or am I mistaken?

Many thanks in advance for sharing your insights.
