Can you help me with my software licensing question?
I have an old Server 2003 domain controller I'm ready to decommission. I notice in Server 2003 there is a Licensing module under Administrative Tools that seems to manage and track user CAL's for the domain controller. I don't see this on my newly promoted Server 2008 domain controller, nor do I see any roles to add it. Does this need to be transferred to my new Server 2008 domain controller or will it all happen when the old server is decommissioned?
I've already transferred all my Terminal Server licenses to the new server.
Thank you!
In 2008, you just need to be sure you have enough CALs for your usage, there is no console as in 2003. This is different from RDS/TS licenses which are managed by the Remote Desktop License server.
You can mix per user and per device CALs in 2008, but it's probably easier to manage a single licensing model.
You should be aware that CALs are version specific - if you are upgrading from 2003 to 2008, you either need to be covered under software assurance, or you need to buy new CALs. Since you commented that you have the 2008 CALs, that's all you need. (As long as you have R2 CALs if you're going with R2.)
2008 R2 Server Licensing FAQ covers most of this.
