If you have a multi host lab where to experiment, you can try if my steps to mimic 3.6 -> 4.0 upgrade flow can be valid. Some of the hard points to verify are: - host reinstall in CentOS 8 based OS correctly joins the original environment oVirt environment still in 4.3 - current 4.3 engine vm can run on 4.4 host - "hosted-engine --upgrade-appliance" command exists for 4.4 - what to do if the space on hosted engine storage domain is not sufficient to contains the new engine vm together with the old one - mixed gluster versions during upgrade don't create problems Gianluca
