I have a client who purchased 100 CUE licenses for an existing CUE. They are in need of adding 50 mailbox licenses. The ordering guide does not specify whether or not the licenses are cumulative. I understand that CUE will only accept 1 license file, however it doesn't make sense that a client would need to purchase a brand new 150 license pak if they already have 100, just to get a total of 150.
Question is, can the client purchase the 50 pak so that they are in compliance with Cisco and then simply download the 150 license from CCO?
