Yes, that makes sense.  Thanks.

Hi,
For CentOS 7, I set the host in global maintenance, and then upgrade 
the engine.
After that, reboot cleanly the engine and set the maintenance back to 
none.
Then you should update the host itself. To do that, you are strongly 
advised to shutdown the VMs first.
If sanlock or vdsm get upgraded in the process, all your VMs will be 
terminated anyway, and this oculd lead to bad results.
So if you don’t have another host, shutdown everything except engine, 
set to maintenance global, update engine, reboot engine, shutdown 
engine, update host, and then set maintenance back to none.
Does that make sense?

What OS are you running the engine on?

In order to not hijack another thread I wanted to separate this

    is different than what the OP on that thread wants to do.
I've been digging through the 4.0 documentation since I'd like to
    upgrade in the not to distant future so I'm doing research and I'm
    confused.
I'm running 3.6.6 in a hosted Engine environment.  My engine runs
    in a vm on the host.  The host is a physical box and the VMs are
    stored on a NAS accessed by an iSCSI LUN,  I have no other hosts
    running so I can not migrate.
According to this link, https://www.ovirt.org/release/4.0.0/, I'm
    told to simply run yum update ovirt-engine-setup and then
    engine-setup but I assume that's for a non hosted-engine
    environment.  I then go to the link for
    Hosted_Engine_HOwto#Upgrade_Hosted_Engine guide and am told to do
    this.
Set hosted-engine maintenance mode to global and other stuff that
    is written assuming I have some place to migrate my VMs to.  I do
    not have another host.
So how do I properly move to oVirt 4.0 from 3.6.6 on a single
    physical host running a hosted Engine VM?
Thanks.
