Hi, Before upgrade make sure your setup upgraded to latest ovirt-4.3.Recommending to keep the workloads on the Virtual Machines as minimal as possible. If you have highly write intensive workloads, then it will take much longer time sync back data which will lead to the longer upgrade window. You should have an additional disk(all hosts) for the new voirt 4.4 hosted engine deployment.
