We are planing to upgrade our cisco call manager 4.2 to 6.1. We have around 2000 users which we need to move them over or upgrade to 6.1
upgrade from 4.2 to 6.1 with no server changes.
create new server cluster with 6.1 and then move the users to the new cluster.(can you provide some samples.)
Can you please help us on what steps we need to take.
