I'll try the --force-setup today if I get a chance, in a worst case
scenario what could go wrong?
When I run the upgrade will it create a DB backup that can be manually
restored if I have to remove all ovirt-engine packages and start from
scratch?
Anyone have some steps on how to go about restoring from the backup
that the "engine-upgrade --force-setup" creates?

Currently I'm running a two node/hypervisor setup with a SAN as my
data storage, but I can't migrate VM's between the nodes due to what
appears to be a bug, which is the reason for wanting to update the
ovirt-engine. As previously mentioned my engine is installed directly
on one of the nodes/hypervisors.

Would it perhaps be a better idea to install a new ovirt-engine onto a
different server and then migrate to the new engine rather than
updating the current one, or am I just being completely paranoid?

We are running mission critical VM's on the install, so I can't risk
something going wrong and the VM's stop running or access to them is
lost.

Thank you very much.

Regards.
