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 > > Von: users-boun...@ovirt.org [mailto:users-boun...@ovirt.org] Im Auftrag von > Michal Skrivanek > Gesendet: Freitag, 23.
