We have a customer currently running exchange 2010. We are planning to migrate to exchange 2016 (since cannot coexist with exchange 2019) and configure DAG.
We would like to know what licences we will need. For exchange servers and CAL's.
There are around 200 users-mailboxes and 5 mailboxes which will be reduced to 2 mailboxes finally by moving mailboxes.
Thank you !
