Our client has a Windows SBS 2003 server, using Exchange 2003, with a few Windows 2003 STD TS servers.
We would like to find out if it is possible to migrate from Windows SBS 2003 with Exchange 2003 to Windows Server 2008 STD with Exchange 2007.
Note: The current setup with Windows SBS 2003 is 32bit. My understanding is that Exchange 2007 must be 64bit in a commercial environment. So most likely the new setup should be a 64bit environment.
Is this migration possible or do we need to rebuild the new servers from scratch?
