Ricky,
I am under the impression that the DB migration was implemented in release 3.6.6.
I might be wrong.
https://www.ovirt.org/release/3.6.6/
What's New in 3.6.6? Enhancement oVirt Engine
BZ 1241149 [RFE] Provide way to preform in-cluster upgrade of hosts from el6->el7. BZ 1332463 [RFE] restore: ensure that 3.6 on el6 backup can be restored on 3.6 on el7 Feature:=20
Allow engine-backup on el7 to restore backups taken on el6.
Reason:=20
engine 4.0 does not support el6. Users that want to upgrade from 3.6 on el6 to 4.0 on el7 have to do this by backing up the engine on 3.6/el6 and restore on 4.0/el7.
This feature, backported from 4.0, allows to do such a migration also in 3.6.
Result:=20
Using this flow, it's possible to migrate a el6 setup to el7:
On the existing engine machine run: 1. engine-backup --mode=3Dbackup --file=3Dengine-3.6.bck --log=3Dbackup.l= og
On a new el7 machine: 2. Install engine, including dwh if it was set up on el6. 3. Copy engine-3.6.bck to the el7 machine 4. engine-backup --mode=3Drestore --file=3Dengine-3.6.bck --log=3Drestore= .log --provision-db --no-restore-permissions 5. engine-setup
Check engine-backup documentation for other options, including using remote databases, extra grants/permissions, etc.
Hi, I tried upgrade my old install to 3.6.6 with same result. I will try downgrade to 4.0 to see what happen.
