<p>Matthew is correct, copying is listed as "Supported with Caveats" at: <a href="http://docwiki.cisco.com/wiki/Unified_Communications_VMware_Requirements" class="OWAAutoLink">http://docwiki.cisco.com/wiki/Unified_Communications_VMware_Requirements</a>; The
caveat being found at <a href="http://docwiki.cisco.com/wiki/Unified_Communications_VMware_Requirements#Copy_Virtual_Machine" class="OWAAutoLink">http://docwiki.cisco.com/wiki/Unified_Communications_VMware_Requirements#Copy_Virtual_Machine</a></p>
<p><br>
</p>
<p>The VM needs to be powered down first and the resulting VM will have a different MAC address (unless it was originally manually specified); so you'll need to rehost the PLM if it is co-res to any VM that you copy.
<br>
</p>
<p><br>
</p>
<p>Where I have seen folks get into trouble with this is where a subscriber is copied, and the user mistakenly thinks that by changing the IP and hostname it becomes unique and can be added to the cluster as a new subscriber. I have also seen users make a copy
of a publisher and change the network details of the copy, thinking it makes a unique cluster and then wonders why things like ILS wont work between the two clusters (and it isn't just because the cluster IDs are the same).</p>
<p><br>
</p>
<p>Having said all of that, I would NEVER do this in production ... maybe that is just me being cautious or old school, but that is just me. Even without changing network details on the copy, I have seen this cause issues with Affinity. At the very least, if
you travel this path I would make sure that the copy runs on the same host and even in the same datastore.</p>
<p><br>
</p>
<p>=== An alternative path ===</p>
<p><br>
</p>
<p>Admittedly, this path is longer and there is a little more work involve but is the safer path, IMO and is what I would trust for a production scenario.
<br>
</p>
<p><br>
</p>
<p>1.) Create a private port group on the host. If the cluster is on multiple hosts, span the port group through a connecting network to the other hosts but DO NOT create an SVI anywhere in the the topology for that DOT1Q tag (remembering to add a DOT1Q tag
on any networking devices between the two hosts and allowing on any trunks between the two hosts).</p>
<p><br>
</p>
<p>2.) Upload Cisco's CSR1000V to the host. If you're not familiar with the product it is at the core and unlicensed, a virtual router with three interfaces by default. Out of the box, it is more than enough to replicate DNS/NTP on your private network which
is all you'll need. Assign the private port group to the network adapters and configure DNS and NTP (master 2) on this virtual router.</p>
<p><br>
</p>
<p>3.) Build out a replica of your production UC cluster on the private network. <br>
</p>
<p><br>
</p>
<p>4.) Take a DRS of the production UC apps and then put your SFTP server on the private network and do a DRS restore to the private UC apps.</p>
<p><br>
</p>
<p>5.) Upgrade the private UC apps and switch your port group labels on the production/private UC apps during a maintenance window.</p>
<p><br>
</p>
<p>Thanks,</p>
<p><br>

What would be your thoughts about taking a clone of every VM. CM, UC, UCCx, CER, PLM, </p>

<p style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: "Times New Roman",serif;">
placing it on another vlan with the same IP's. NAT it as it goes onto your network so it has access to NTP, DNS, AD, etc.</p>
</div>
<div>
<p style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: "Times New Roman",serif;">
</p>
</div>
<div>
<p style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: "Times New Roman",serif;">
do your upgrade on the clones.</p>
</div>
<div>
<p style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: "Times New Roman",serif;">
</p>
</div>
<div>
<p style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: "Times New Roman",serif;">
Then in VM ware shut down the originals,and change the Vlan (on the clones) back to the production vlan for your voice cluster.</p>
</div>
<div>
<p style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: "Times New Roman",serif;">

<div>
<p style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: "Times New Roman",serif;">
it would be like a telco slash cut. 10 minute outage as you move from one version to the other.</p>
