My boss is telling me that I need to upgrade our cisco callmanager cluster, he is telling me that we need to upgrade our original cisco callmanager 4.2.1 to 4.2.3, now i know that he is been messing with this issue for a while, I want to make sure everything will go smoothly, although when i go to the publisher and HELP>ABout Cisco callmanager>select details this is what i got
Cisco Callmanager System Version:4.1(3)sr3a
Cisco Callmanager Administration Version:4.1(0.11)
Cisco Installation ID:4.1(3)sr3a
So who is right? According to this info Our cisco callmanager is not at 4.2.1? is cisco callmanager 4.1.(3)sr3a
Is there anyway to find out the exact Os version and patch currently installed in the callmanagerS?
Seems to me that the win-os-upgrade-k9.2000-4-2.exe was already applied to the ccm ?, based on the information that i have provided here what will be the best thing to do and the steps to proceed with the upgrade
thank you for your time
