[cisco-voip] IM&P Upgrade Steps during CUCM upgrade

[Ryan Huff]

This is what I do for an in-place upgrade with no other changes (hostname, IP address.. etc).

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.

I do the pubs individually, then I’ll do a couple subs at a time .. etc.

Next I Switch version on the pubs; cucm, imp then the subs.

On the switch version, I wait till one node is fully up (tomcat started) before switching another.

May not be as efficient as it could be, but has kept me out of trouble thus far; plan your dive, dive your plan.

I’m reading the upgrade guide, specifically, the time sequencing:

and it mentions upgrading the IM&P publisher (to inactive partition) at the same time as upgrading the subscribers. Then doing a switch version on the IMP pub at the same time as the CUCM subs.

Anyone do this parallel type upgrade before?

Sure would save a lot of time.
