I want to upgrade a client call manager from version 6.1.2 to version 8.5. It is my understanding that both versions run different licensing model.
CUCM Ver 6 runs DLU while CUCM runs either UCl or CUWL. The customer expects the upgrade to cover up for 7000 users though they currently have 1800 users. They currently have about14000 DLU licenses and 6 nodes.
