We would like to migrate our CallManager solution from UCM 7.1.5 to UCM 8.6. We are using the DUL license mode for devices and we would like to change to the license mode to UCL. Could you please give me some explanation or send the link for information about this issue? We would like to know all the cost related to the migration process namely software/license/hardware acquisition costs.
We have a cluster made of the following server:
- 2 MCS-7845 Server;
- 1 MCS-7835 Server.
