In fact unless you are going to have a DNS server on the dead network then you will cause problems by configuring a DNS server.</div><div><br></div><div>Since the servers get their hosts files configured during the sub install as long as no DNS is configured and your System->Server entries are hostnames then you can leave the new servers on a live network (just with different IPs than the production servers). They won't talk to anything they can't resolve and without DNS the only thing they will resolve is the other nodes of the cluster. You'll want to watch out for multicast MOH if you do this, but otherwise it should be safe.</div><div><br></div><div>The rest of your procedure looks fine, maybe a bit of overkill, but definitely the safe way to go.</div><div><br></div><div><div>
