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?
Just wanted to add a short note to the great info from Arvind. One cautionary note to keep in mind that this customer may not have fully thought through is that the Feature set in CCM 5.x is not the same as the Feature set in CCM 4.2 If the customer is using some of these features in 4.2 they won't be happy with the 5.x train :(
Here is a DLU overview;
Device licenses are sold in increments of device-license units (DLU's). Device-license units are assigned to each device connected to Cisco Unified CallManager 5.0. Each device is assigned a unit number based on the type and capabilities of the device. Devices with more complex and high-end capabilities are assigned a higher number of units compared to devices with basic capabilities,
Here is the DLU breakdown;
Cisco Unified IP Phone 7902G = 1
Cisco Unified IP Phone 7905G = 2
Cisco Unified IP Phone 7911G = 3
Cisco Unified IP Phone 7912G = 3
Cisco Unified Wireless IP Phone 7920 (no battery) = 4
