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:
Allow engine-backup on el7 to restore backups taken on el6.
Reason:
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:
Using this flow, it's possible to migrate a el6 setup to el7:
On the existing engine machine run:
1. engine-backup --mode=backup --file=engine-3.6.bck --log=backup.log
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=restore --file=engine-3.6.bck --log=restore.log
--provision-db --no-restore-permissions
5. engine-setup
Check engine-backup documentation for other options, including using
remote databases, extra grants/permissions, etc.
