Michal,

  thank you for your quick response! I am running 300+ VMs so any other (safe) option would be very welcome…

and are they all in a 3.5 cluster?
Your priority should be to get them to 3.6 compatibility prior upgrading to 4.0, then once in 4.0.3+ there is a safe-enough way how to properly update 3.6 to a 4.0 cluster level.

otherwise, any <3.6.7 would allow you to do that or there is a manual postgres workaround mentioned in that bug which you can try/risk - basically as long as you can reboot those VMs in a foreseeable future(prior to use any of the new features) you can follow the manual workaround and upgrade to 3.6….just make sure you stop and start them eventually



All the best,
Simone

Hi all,

  I am trying to upgrade an oVirt installation (3.6.7.5-1.el6) to 4.0. My datacenters and clusters have 3.5 compatibility settings.

I followed the instructions from http://www.ovirt.org/documentation/migration-engine-3.6-to-4.0/ but cannot proceed in engine-setup as 3.5 compatibility is not supported.

When trying to change cluster compatibility from 3.5 to 3.6 I receive “Cannot change Cluster Compatibility Version when a VM is active. Please shutdown all VMs in the Cluster.” According tohttps://bugzilla.redhat.com/show_bug.cgi?id=1341023 this should be fixed in 3.6.7. Any ideas?

this bug is blocking it, later bugs
(linked from there) allows it, though there are other issues…so if you have an option to shut them down please do so.
note those are RHEV bugs, not oVirt bugs so the exact build may differ

Thanks,
michal




Best Regards,
Simone Bruckner
