Upgrade steps i found out...


"      Run BARS, and take full backup from the call manager 4.2.
"      Take the Background images, Ring tones, and the MOH to your local disk.
"      Take all phone types configuration through BAT.
"      Determining Registration Counts By RTMT.

"      Check the Services, which are running and which are not.
"      Take the Servers Names
"      Connect all the phones in the site to the System and be sure that all of them are registered.
"      Add 50 phones 7970, 7961, 7962, 7965, 7941, 7942, 7945, 7906 with dummy MAC(for licenses) Addresses.
"      Take the DHCP Backup if you have

"      Check if all the phones will register with the subscriber if you disconnect the publisher before proceed with the upgrade.
"      Run the Upgrade Assistant Utility on the publisher first then the subscriber, don t run it on both at the same time. If there is no problems continue to the next step if yes solve it then run the utility again then continue.

"      Configure the DHCP on the Publisher Server.
"      Upload the Servers license.
"      Run the services and let all the phones to be register with the Publisher and check the stability of the system. All the features should be work before upgrade the Subscriber.
"      Upgrade the Subscriber with same procedure of the Publisher but don t select it as the first node.

Without the exact CUCM version you really cannot get an answer


Table 4     Supported Cisco Unified Communications Manager Upgrades for Release 7.1(x)

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr.html#wp108792


As for mixing versions that's most definitely NOT possible. ALL servers in the cluster must run the EXACT same version.
