[ovirt-users] Cannot restore engine from 4.3.9 to 4.4.3

Hi 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). # engine-backup --mode=restore --file=/exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup --provision-all-databases Start of engine-backup with mode 'restore' scope: all archive file: /exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup log file: /var/log/ovirt-engine-backup/ovirt-engine-restore-20201111031500.log Preparing to restore: - Unpacking file '/exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup' FATAL: Backup was created by version '4.3.9.4' and can not be restored using the installed version 4.4.3.11 Complete content of the restore log file: 2020-11-11 03:15:00 23143: Start of engine-backup mode restore scope all file /exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup 2020-11-11 03:15:00 23143: OUTPUT: Start of engine-backup with mode 'restore' 2020-11-11 03:15:00 23143: OUTPUT: scope: all 2020-11-11 03:15:00 23143: OUTPUT: archive file: /exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup 2020-11-11 03:15:00 23143: OUTPUT: log file: /var/log/ovirt-engine-backup/ovirt-engine-restore-20201111031500.log 2020-11-11 03:15:00 23143: OUTPUT: Preparing to restore: 2020-11-11 03:15:01 23143: OUTPUT: - Unpacking file '/exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup' 2020-11-11 03:15:01 23143: Opening tarball /exports/data-t2/backups/ovirt-engine-backup-20201018124037_pre-upgrade.backup to /tmp/engine-backup.UAcLerghwY 2020-11-11 03:15:01 23143: Verifying hash 2020-11-11 03:15:01 23143: Verifying version 2020-11-11 03:15:01 23143: FATAL: Backup was created by version '4.3.9.4' and can not be restored using the installed version 4.4.3.11 regards, Toni Feric
