[ovirt-users] Re: Migrate from Centos8 to Centos9

With the current versions, you cannot migrate from Centos 8 to 9. It cannot be solved with engine backup, the only solution is to export the VMs to OVA or choose the export to domain option, then do a clean install with a Centos 9 ovirt engine, and then use either the OVA or the import domain. Both solutions will definitely cause downtime.
