about a n hour ago I just tested to setup ovirt 3.6, then upgrade it, 2 nodes: host and ovirt on separated machines.
very smoothly upgraded, first engine upgrade then host upgrade.
The only trouble on hosts is that some pacages are still reffering to ovirt-3.6 repository even ovirt-4.0 is there.
it is simple to fix: yum list installed| grep ovirt-3.6 then removing all possible packages
next reinstall host from GUI.
Thats it.

Hi,
I am also interested to upgrade my system from centos 7 ovirt 3.6.7 to ovirt4, are there any preferable order to upgrade? Host then engine? or engine then host?
thanks,
Arman.

Is it the same in case of single host with CentOS 7 and hosted engine?
Any caveat in this scenario?
