This is what I do for an in-place upgrade with no other changes (hostname, IP address.. etc).
<div><br>
</div>
<div>I do the cucm pub first (obviously), then imp pub (which is more like a cucm sub for upgrade purposes), then all the cucm and imp subs; everything into the inactive pt.
<div><br>
</div>
<div>I do the pubs individually, then I’ll do a couple subs at a time .. etc.</div>
<div><br>
</div>
<div>Next I Switch version on the pubs; cucm, imp then the subs.</div>
<div><br>
</div>
<div>On the switch version, I wait till one node is fully up (tomcat started) before switching another.</div>
<div><br>
</div>
<div>May not be as efficient as it could be, but has kept me out of trouble thus far; plan your dive, dive your plan.<br>
