Yes, it's in.
It's tracked here:
https://bugzilla.redhat.com/show_bug.cgi?id=1240466
https://bugzilla.redhat.com/show_bug.cgi?id=1235200

We have still something to improve on corner cases if the hosts you want to
filter out in the restore process were not in maintenance mode when you
took the backup but the functionality is there.

I read through that and it makes sense.  It also said that moving the
hosted engine's storage was a 4.1 feature, but I didn't see it on the
release notes for RC 2.  Is it still planned for 4.1?  Do you have the BZ
handy so that I can track it?

[ovirt-users] Migrate hosted engine to a new storage domain

[Logan Kuhn]

Hi

We are planning on moving to a different storage solution and I'm curious,
is there a way to migrate the hosted engine's storage domain to the new
solution?  It's NFS currently and can be NFS on the new storage as well.

>From what I've read it looks like it should be possible to

   1. Take a full backup of the engine VM
   2. Deploy another hosted engine VM with hosted-engine --deploy
   3. Install/configure CentOS 7.3
   4. Deploy new engine with engine-setup
   5. Then restore the backup into the new VM.

What I'm not sure of is if that backup will contain enough of it's data to
restore to a completely different storage domain?

Also, the engine database is on a remote server, the data warehouse service
and all other aspects of the hosted engine reside on the VM.

Thanks,
Logan
