<div class="">I’ve not done CUCM project work in quite a while, so may be completely off, but what about making this scenario supportable:</div>
<div class=""><br class="">
</div>
<div class="">Complex cluster say, 1 Pub, 6 Sub, 2 TFTP</div>
<div class=""><br class="">
</div>
<div class="">Install new software to inactive partition on all nodes, once complete reboot part of the cluster:</div>
<div class=""><br class="">
</div>
<div class="">1 Pub - new version</div>
<div class="">3 Sub - new version (primary subs)</div>
<div class="">
<div class="">1 TFTP - new version (primary TFTP)</div>
</div>
<div class="">
<div class="">3 Sub - old version (secondary subs)</div>
<div class="">1 TFTP - old version (secondary TFTP)</div>
<div class=""></div>
</div>
<div class=""><br class="">
</div>
<div class="">Phone registers to upgraded primary subs, once everything working/stable/tested, flip remaining (secondary nodes)</div>
<div class=""><br class="">
</div>
<div class="">Maybe too complex for this split version to be workable, or not really much different than flipping all nodes, but may allow the phones to stay online with minimal disruption as long as all external elements strictly follow the primary/secondary
node configuration.</div>

<div dir="ltr" class="">If only there was an upgrade process wherein you install the new version to an inactive partition, and then could switch to the new version when you're ready. /sarcasm
<div class=""><br class="">
</div>
<div class="">But seriously though, everyone in this thread is essentially coming up with their own clever way of replicating the promise Cisco failed to deliver on, which is performing your upgrades during production on the inactive partition and then switching
versions in a maintenance window. If they would have only held themselves to a higher standard, we wouldn't need this complex of an alternate solution.</div>

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