Ahh, that looks better.  I was looking at this:

https://www.ovirt.org/documentation/migration-engine-36-to-40/

which just kind of glosses over how to upgrade the OS. :)

I do usually use my custom CentOS install (rather than the appliance);
is there a way to do that?

Also, is it normally recommended to upgrade one major release at a time?
In other words, aside from the engine CentOS6->7 step, would upgrading
from 3.5 to 4.1 need to go through 3.6 and 4.0 along the way?
