I have a Windows Server 2003 environment (2 DCs, an Exchange Server (2003), and a Web Server).
Is it ok to purchase Server 2008 and perform an "upgrade" (if this is even an option), or better to do a fresh install and recreate the AD manually (adding groups, users, etc).
I have a very small network (5 users). I'd prefer to do an upgrade, as it would save me from having to recreate the AD from scratch, but I would like to know what the best practice is.
Also, would upgrading effect my Exchange Server?
