I have a client that has his IP Telephony solution running in Cisco CallManager 4.2. He has now purchased Cisco Unified Communications 5.1. I know there's is no direct upgrade from 4.2 to 5.1. So I'll have to rebuild the database to the new 5.1 server. Even though it's cumbersome it is pretty straightforward.
My big issue is related to licenses. Obviously the client has the licenses associated with the phones on 4.2. But how do I convert that, without DMA, to some .lic file for 5.1?
Any ideas if this is possible? If it is, how can I do it?
