I currently have a exchange 2003 server, running on Windows 2000 SP4. the Active Directory connector is 2003. I am going to purchase new server hardware and install Exchange 2010 on it. What is the best way to implement the new exchange 2010 server? the new server will be running on Server 2008 R2.
Also from reading about exchange 2010, some people use multiple servers for each role. Do I need to have more than 1 server? The server I have will be pretty robust and plenty of memory.
