actualy what i want is to prevent misuse the phone by unathorized persons.so can i update my ccm v4.0 to v4.1 without changing any configuration or can i restore my v4.0 backup file direcly to the ccm v4.1
you can upgrade from 4.0(2a) to 4.1(3) to have the FAC and CMC features. you may also think of going to 4.2(3) for that matter. simply check the HW compatibility to make sure your server supports the version.
usually all you need to upgrade is the OS beforehand
BARS backup and restore needs to be done on the EXACT SAME VERSION, meaning EXACT SAME SR or ES. so no, you cannot backup 4.0 and restore on 4.1
