We currently have a client that has 2 sites. Master site is using Windows SBS2003 and the remote site is Server 2003 SP2.
The Active Directory is being replicated between these two sites.
We need to upgrade the Master sites server and are considering a SBS2011 migration.
What we need to know is if the remote site server can stay as a Windows Server 2003 SP2 server or will this need to be migrated to a Windows 2008 R2 server.
