Establish functional teams with experts in directory services, administration and management, core
operating system (OS), networking, applications, and hardware compatibility. Have these teams
evaluate Windows Server 2003 SP1. Plan on four to six months to correctly plan your upgrade
strategy. Make clear assignments and verify progress along the way. The planning process for a
project of this scope is a critical piece in its success.
Fix any problems in your Windows NT 4.0 and/or Windows 2000 environment and verify that your
Windows Internet Naming Service (WINS) works properly. WINS will be necessary on your system
until all clients are Active Directory aware. Identify the resource domains to be collapsed into the
Active Directory domain structure, and check for duplicate names across the entire network. Audit
your security environment and determine how global groups can help with the upgrade process.
Understand the Microsoft supported upgrade paths for moving to Windows Server 2003 SP1 from
Windows 2000 or Windows NT 4.0 as seen in Table 1.

IMPORTANT:
You must move to an equivalent or higher operating system during
the upgrade. Downgrading to a less powerful operating system is
not recommended.
Once you decide where you are, how you got there, and what is available, determine where you
want to be and how to get there. Who will upgrade first? How will you determine when the next
group is ready to upgrade? What security issues are most important? How long can you allow for the
full upgrade? Develop a roadmap with clearly defined action programs to make sure you have a
strategy that can work. Your strategy should include checking the HP Windows Server 2003 website
on a regular basis for new information. HP Services can help you plan your upgrade to Windows
Server 2003 SP1.
