If your target is upgrade from 4.3 to 4.4 you have to do an "application" backup of the 4.3 engine (see the link at the bottom) and restore it on the new engine in 4.4, that is a scratch install on a new system, but can have the same ip/hostname as the old engine server, so that it could be transparent from an user access point of view. Already done both on oVirt and RHV with external engine, local database. The old engine and the new one are two vSphere virtual machines. You can install the new engine based on RH EL 8 with temporary network parameters and then as soon as you have completed the backup of the 4.3 one and copied over it you can shutdown the 4.3 engine server, to keep at a minimum the absence of an engine for the environment that anyway doesn't compromise the workload of your virtual machines. Of course HA reactions or live migration are not possible in this time frame without an engine. The restore and the reconfiguration take minutes if you prepare the new engine server in advance.
