A small report from my side: After doing your instructions I get some error messages from engine-backup. I have to remove the folders /var/lib/ovirt-engine-reports, /var/lib/ovirt-engine-dwh, /etc/ovirt-engine-reports and /etc/ovirt-engine-dwh manually. Then engine-backup works again. Otherwise nothing has struck me.
