CUCM Upgrade from V8.5 to V9.1

Hi Team,

I plan an upgrade from current CUCM V8.5 SU3 (8.5.1-13900-5) to actual V9.1(2) (9.1.2-10000.28).

I am already virtualized and used the unrestricted 9.1 image from CCO, as the current installation also

is based on the unresctricted image.

My current VM Image for CUCM V8.5 is based on:

RHEL 4 32-Bit, 80 GB Disk, 6GB RAM, 2 x vCPUs (Intel Core i7 CPU 860 2,8 Ghz)

For now, I started the upgrade on a testmachine, just to test the RU upgrade and see the behavior of the ELM.

The upgrade failes with the message:

Selected Upgrade is disallowed from current version

From what I see in the compatibility matrix (table 4)

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr1.pdf

there should be a direct RU upgrade path.

btw: I know that for real production vCPUs with 3,6 Ghz are needed for CUCM 8.6 and later, but I hope that I could test the upgrade

process based on this testmachine, especially since the error message above is complaining regarding sw-versions and not hw-resources.

any idea is appreciated,

thx Alfred

I'd stronlgy suggest you to read the RNs from 9.1(2) prior to doing anything to get all the necessary info and changes you're required to make after the upgrade.
