To avoid boring you out of your mind I will will condense my troubles. We are in a SLOW process of upgrading from CUCM 8.5 to 10.5. There are many factors involved, so we have to do this a department at a time. The dilemma I face is:
The database was migrated from 8.5 to 10.5 back in December 2015, but most phones are still pointing to 8.5 and thus registered to that cluster. We are a hospital and thus make 100's of database changes a day. I need an efficient way to compare the phone configurations for groups of phones on 8.5 and if the configs do not match update them on 10.5. Is there a recommended solution for this?
