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.

For the repo part I posted a question for clarification:

http://lists.ovirt.org/pipermail/users/2016-July/040910.html

see there for follow ups

In my case for single host environment with both host and hosted engine (deployed as appliance) on CentOS 7.2 and storage domains on NFS served by the host itself, this is the flow I followed to bring a 3.6.5 environment to 4.0.

Problem still here is inability to upgrade the only existing cluster to 4.0 and then the datacenter to 4.0

Currently not possible due to :

https://bugzilla.redhat.com/show_bug.cgi?id=1351533

To update I kept valid what explained in the thread started here:

http://lists.ovirt.org/pipermail/users/2016-June/040649.html

yum update doesn't propose ovirt 4.0 packages

So I installed ovirt 4.0 repo (as in clean install description) and disabled 3.6 ones.

yum update "ovirt-engine-setup*"

gives

Is this ok [y/d/N]:

Then I put in place vdsm.conf.rpmnew changing inside it

[addresses]

management_ip = 0.0.0.0

This is necessary because I have disabled ipv6 at system os level and this setting forces vdsmd to listen on IPV4, that is not the default.

Other settings I had in 3.6 vdsm.conf (put in by initial installation) were not explicitly inserted because they already are the default ones. they are:

ssl=true

and

management_port = 54321

reboot host

after some minutes engine vm starts ok

Wait for stabilization.

All seems up and I'm able to boot and connect to my VMs.

At the beginning the host results as needing for upgrades, but after couple of minutes the engine detects that it is ok, from a components version point of view.

In webadmin portal I still see the host with exclamation mark on side of it because of course I've not configured power management in this single host environment.

Only thing I don't understand is that I also see an icon on side of host (I don't understand its graphic; it seems a crown, or a tower ) and when I mouse over it I see the tooltip

Action Items

But I don't understand how should I manage it...
