I just tried to restore my engine backup taken from release 4.3.9.4 to a newer oVirt installation release 4.4.3.11.

The restore process fails with a FATAL error.

I was under the impression that backups from all 4.3 versions were supposed to be restorable on 4.4.

My installation is a single-box all-in-one (Standalone Engine installed together with oVirt node).
