We have 4 different DC's in 2 different sites. &nbsp;All DC's are 2003. &nbsp;Is there anything I need to do before I go into AD UC and &quot;raise the domain function level&quot; to Windows 2003?<br />

We have 4 different DC's in 2 different sites.  All DC's are 2003.  Is there anything I need to do before I go into AD UC and "raise the domain function level" to Windows 2003?
Where do I raise the forest level? Do I do this before or after raising to Windows 2003 move?
I ran NETDIAG and DCDIAG without issues.


Switching from Windows Server 2000 mixed mode to Windows Server 2003

Windows 2000 is an operating system for use on both client and server computers. It is the successor to Windows NT 4.0, and is the last version of Microsoft Windows to display the "Windows NT" designation. Four editions of Windows 2000 were released (Professional, Server, Advanced Server, and Datacenter Server) that shared a core set of features, including many system utilities such as the Microsoft Management Console. All versions of the operating system support NTFS 3.0, Encrypting File System, as well as basic and dynamic disk storage. The Windows 2000 Server family includes support for Active Directory services, Distributed File System and fault-redundant storage volumes.

Windows 2000

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
