Direct upgrade from 4.3 to 4.5 should work fine but direct upgrade from 4.2 backup is not working. As for the host, oVirt Node 4.5 is supposed to be compatible with ovirt engine >= 4.2. Thank you Sandro. I’m following the instructions over here: https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_the_Manager_... https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_Remote_Datab... I had to upgrade Postgres to version 10, on the SelfHosted Engine to proceed. Just followed the “remote database procedure” even without a remote DB. I just have one more question: to do the jump from 4.3 to 4.5 on the engine the only way is restoring a backup right? Since 4.5 is based on EL8. I cannot do the yum update ovirt\*setup\* method right?

Is there other way?

Also during the host upgrades, I understand that I can run oVirt Node 4.5 with Engine 4.2 (and now 4.3), which is awesome. But is there a path where I can upgrade the engine to the latest version and them move the hosts?

I have those questions because I can’t see where or when the OS upgrade will be done on the SHE during 4.3 -> 4.5.
