I have a domain with a Windows 2003 R2 server.
The Domain is in 2003-level.
Now I want to install a Windows Server 2012 R2 domain controller that is going to replace the 2003-server.
I have both Windoes XP and Windows 7 clients in the domain.
Are there anything I should consider when introducing the 2012 R2 server ?
Does XP clients work with the 2012 R2 server ?
