I'm looking at a setup where there is one remaining 2003 Domain controller. It has the CA role and IAS role. It is configured to authenticate Wireless and VPN. We want to retire this domain controller and upgrade the domain functional level to 2008. With
that I have a few questions.
1. If I were to just demote the server would the IAS and CA functionality still work? Would it work if the domain functional level was raised?
2. If I could just demote and everything would still work is that a bad idea? Should I just migrate all of the roles to a new 2008 Server?
3. If I migrate everything to a 2008 Server it does not need to be a DC correct?
If possible I want to see what options are available.
thank you,
