[cisco-voip] UC 4.x migration to 8.x

[Robert Hass]

Hi
I have UC environment consist:
- Cisco CallManager 4.2(3)sr4b - 2 servers
- Cisco Unity 4.2 - 1 server
- IPCC Express installed on subscriber server
- 400 phones (end-users)
- 6 conference room-phones
- 2 fax machines
- all servers are 7825-I3

We want to upgrade all environment to latest 8 version. I found nice
'3 & 3' promotion but can We migrate to CUWL using this promotion or
only UCL ?
After upgrade I see that I cannot use IPCC Express on same server with
CUCM - Do I have buy MCS new server for IPCC Express ?
Is 5-users license for IPCC Express is included for CUWL or UCL after
migration ?
