I'm trying to determine how the Communications Manager System Version matches up with the Version labeled on the Installation DVD. For example, in my CUCM I have a system Version of 220.127.116.110-3 and I'd like to make sure I have the correct installation DVD for my current version but all I'm finding are DVDs that say "Cisco Unified Communications Manager 6.0(1a)". How does 6.0(1a) relate to a version of 18.104.22.1680-3?
I've viewed the Communcations Manager Compatibility Matrix at http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr.html#wp76346 and I can see that for version 6.0(1a) there is a System Version of 22.214.171.1240-4 but I could not find any correlation to my current system version which is 126.96.36.1990-3.
The reason why I'm going through this exercise is because I'm getting ready to upgrade my system to a later release due to a bug in the current version I'm running and I'd like to make sure I have the original media on hand in the event of a worse case scenario.
Can anyone tell me how I can confirm that my media is correct in case I need to reinstall my current version or just explain to me in general how the 3 or 4 character version of the CUCM (the one that see on Installation DVDs like 6.0(1a)) relates to the 8+ character system version (the one that you see when you log into the CUCM Admin page like 188.8.131.520-3)?
Any help is much appreciated.
