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.
Ours failed at this as well. We had to upgrade the vmtools prior to doing anything. This allowed us to select CentOS 7. Everything after that went smoothly.
if you are having this problem, before the upgrade change the security status to permissive: utils os secure permissive on both pub and sub.
