I migrated from 4.3 CentOS 7 to 4.5 Rocky 9. I migrated the engine from one server to another using a backup/restore. I reinstalled the hosts without loss because I have a SAN.

Hi,
I’m working on upgrading an oVirt 4.3 cluster to the latest 4.5 version. So far, I’ve successfully performed a test upgrade of the oVirt Engine from 4.3 (CentOS 7) to 4.4 (AlmaLinux 8.10).
I’ve encountered some noVNC issues, as described here: https://forums.oracle.com/ords/apexds/post/olvm-manager-vm-console-novnc-exc...
I’ll probably leave this issue unresolved for now, as I’m planning to continue with the upgrade process.
For the next step, I’d like to ask if anyone has experience installing and running an oVirt 4.5 cluster (both engine and hosts) on AlmaLinux 8.x. So far, it seems that I might need to upgrade the OS to AlmaLinux 9 as well, possibly using ELevate.
If anyone has recently completed a similar migration, I’d really appreciate any tips or recommendations.
Best regards, Pavel
