Re: [ovirt-users] Query about running ovirt-4.2.1 engine support 3.x nodes ?

Sorry to ask again, But I can see from the link below the that nodes and engines should work between minor number upgrades.

But is ovirt 4.2.x backward compatible with, say, 3.6 nodes. Does anyone know ? Is this documented anywhere ?

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)
