Can you tell, as I understand CUCM backup stores .lic files and when I restore those files will be there, if I change new hardware's mac address to an old mac address witch where used in old server, will it work?
It would not be a supported configuration so it would not be recommended.
It is not possible to change the server MAC address using the normal accounts created during CUCM installation - it may be possible if you create a root account but this is not a good thing to do on a production system. If you really want to try then the link below may be helpful.
