we are running CUC 10.5 and doing RU upgrade to 12.5, i have installed the ciscocm.cuc_upgrade_12_0_v1.2.k3.cop.sgn and ciscocm.version3-keys.cop.sgn cop files as per the upgrade guide and then started the upgradation of 12.5 but it fails. i have attached the screenshot and install log.
even though CUC 10.5 is still compatible with CUCM 12.5 and working fine but eventually we have to upgrade to 12.5
any suggestion will be highly appreciated.
yes I did change the os to "CentOS 4/5 or later (64bit)" as on current vmtools i do not have the option to select centOS 7 so once it will upgrade then will update the vmtools and then will select it.
I have did the same for CUCM and IMP nodes and they have upgraded without any issue.
There are 3 cop files to install (you only listed 2). Did you install "ciscocm.refresh_upgrade.cop" too?
This is for 9.x...so nevermind.
