</span>It seems I have to create a new cluster, migrate a host over, migrate a<br>
few VMs, and so on until everything is moved over. This really isn't<br>
ideal as the VMs have to be shut down and reconfigured, but doable.<br></blockquote><div>There is no better way, management network cannot be changed once there are Hosts in Cluster.<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

What I seem to be stuck on is changing the cluster on the HostedEngine.<br>
I actually have it running on a host in the new cluster, but it still<br>
appears in the old cluster on the web interface with no way to change this.<br></blockquote><div>Martin, is such thing possible in HostedEngine? <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Any hints, please?<br>
<br>
This is on oVirt 4.1.9. Upgrading to 4.2.1 is not out of the question if<br>
it's likely to help.<br>
<br>
Thanks,<br>
