Could you please help me with a such question.
I've installed a new CUCM server ver. 12 and want to upload backup from my old server ver. 10.5.
Is it possible or I need to upgrade my old server from 10.5 to 12 and then make backup and upload it on a new server?
Does my backup file contain such information as ip address, hostname, certificates, administration users, security password? Could it change this parameters on my new server after backup upload?
A restore will only work on the exact same version from which it was taken.
The DRS guide explains the procedure, and what information needs to match for a backup to be restored, review the online documentation.
Yes, you can change whatever you want after you restore.

You can always temporarily remove your ESXi License and run in Evaluation mode if your license is not allowing PCD API connections.
