Hello,

 

The best option is go through the upgrade guide:

 

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/upgrade/12_5_1_SU1/cucm_b_upgrade-and-migration-guide_1251_SU1.html

 

Points to remember

- 12.5 will have cloud based PLM

- Hardware compatibility is changed

- IMnP should be upgraded as part of CUCM

Go through the Compatibility Matrix CUCM 10.5 to 12.5 

Are you going to Use PCD or Direct Upgrade?

Take the UID license file details, if you have an active contract which helpful for converting 10.5 to 12.5 licenses.

Check Any deprecated Phones models registered?

Take a DRS backup of existing cluster.

Follow pre upgrade and Post upgrade checklist.

Mandatory reading for an upgrade, all for the target version:

A) Upgrade and migration guide

B) Release notes

C) README from OVA

 

HW and ESXi compatibility also has to be checked, use the Cisco Collaboration Virtualization for that.

 

After thoroughly reading the above docs, you will have all the information that is required for this, requirements, and the procedure.
