[ovirt-users] upgrading from 3.6 -> 4.1, vm restarts at 4.0 mandatory?

I’m upgrading my main cluster from 3.6 to 4.1, and I’m currently at 4.0. I’ve upgraded the cluster and datacenter compatibility versions to 4.0, and now all my VMs are pending restart to update their configs to 4.0. My question is “Do I need to do this here, or can I go ahead and update the engine and host nodes to 4.1, update compatibility to 4.1, and then restart all the VMs to get them on 4.1”? Or is that unsafe, will I screw them up if I go to 4.1 compatibility in this state? Thanks, -Darrell
