Indeed.
But is ovirt 4.2.x backward compatible with, say, 3.6 nodes. Does anyone know ? Is this documented anywhere ?
You can search the release notes pages of 4.2.z releases for '3.6' to find relevant bugs. Just _using_ such hosts, should work. Adding a 3.6 host to a 4.2 engine will likely break. It's definitely not intended to be used for long times - you are encouraged to upgrade your hosts too, soon after the engine. If you plan a very long transition period, I suggest to create a list of operations you might want/need to do, and test everything in a test environment.

Hello All,
I have two hopefully easy questions regarding an ovirt-4.2.1 engine support and 3.x nodes ?
1) Does an ovirt-4.2.x engine support 3.x nodes ? As This page states:
"The cluster compatibility is set according to the version of the least capable host operating system in the cluster."
https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks/
Which seems to indicate that you can run say a 4.2.1 engine with lower version nodes, but is that correct ?
2) And can you just upgrade the nodes directly from 3.x to 4.2.x as per these steps ?
1. Move the node to maintenance 2. Add 4.2.x repos 3. yum update 4. reboot 5. Activate (exit maintenance)
This should work. You can also use the admin web ui for updates, which might be better, didn't check recently. See also e.g.: https://bugzilla.redhat.com/show_bug.cgi?id=1344020 Best regards, -- Didi
