Hello Andrei,
as I know, you need to have to have your cluster with at least 4.3
version to migrate to 4.5. I was facing the same problem with (not so)
old hardware. and i started to do step by step migration.
it means i created new cluster with fresh configuration with ovirt 4.5
and cluster compatibility version 4.7 next to old one with 4.4. Iit is
a good opportunity to prepare whole cluster configuration in ansible for
me :D
Then I migrate VMs one by one from old cluster to the new one. When is
one node free on old cluster I reinstall it and add to new cluster.
Maybe it is not the fastest solution, but i can arrange maintenance for
each VM.

Hi,
I have cluster compatibility version 4.2, due to some old nodes.
From what I remember in oVirt 4.5 release notes (correct please, may be wrong
here), oVirt engine 4.5 requires cluster compatibility version >= 4.3.
Please clarify. Thanks.

Hi,
I have engine version 4.4.10.7-1.el8, is it possible to set up new node host on
CentOS Stream 9, or I need to upgrade engine to version 4.5 first (which is not
right now possible because of some quite old nodes) ?
yes, you generally need the latest version
You can keep your old nodes old, 4.2 based nodes are still working with 4.5
Thanks
Andrei
