CC3 Server 2003 to Server 2008
I have a CC3 network (for admin and curriculum) with 6 DC's, 1 Exchange, 1 Sims server.
We are going vanilla with server 2008 (virtualised). We have good scope for current & future servers.
We want to do a staged approach i.e do admin first then move the various curriculum roles over.
My biggest stumbling block is exchange as I need to leave it referencing the server 2003 / CC3 Active Directory but also need it to see my new domain on server 2008.
So the Exchange server remains a member of the CC3 network for now serving the CC3 student Mail but also serves the new admin network at the same time.
I plan to set up a trust between the 2 domans but how do I get Exchange (2003) to work with my new AD in server 2008 as well.
