Upgrading to Windows 2003

Upgrading to Windows 2003

This section covers the various aspects of the upgrade process.

Planning an Upgrade

To effectively plan for the change, you need to understand the differences between your current configuration and your Windows Server 2003 configuration. Moving from Windows NT 4.0, DNS becomes the primary method of name resolution, and your network administration becomes much more granular and localized. It might seem extremely complex at first, but good planning eliminates much of the difficulty. To effectively plan for these changes, find and update your network map to determine how and why your network looks as it does.

Along with assessing your network, review the applications that you plan to use after the upgrade. Use the review processes outlined in the next two sections.

Network Assessment

The following series of questions will give you an idea of how to conduct your assessment. Keep in mind that each environment is unique and may require additional considerations.

• What domains do you have and why?

• Does the structure work internally?

• What changes could make network use easier?

• Will certain changes make your network Administrators more efficient?

• What are your security needs?

• What are your bandwidth needs?

• How do you use or plan to use the Internet within your organization?

Look at the entire network infrastructure to establish what improvements should be made before the upgrade begins.

Application Assessment

Look at your current applications and determine whether they will operate in a Windows Server 2003 environment or whether you need an upgrade or replacement. Ask yourself the following questions:

• How are the applications used?

• Which groups use them?

• Will this make a difference in your network structure?

Are there similar applications in use elsewhere in your organization that are more likely to be compatible with Windows Server 2003? Take time to investigate Windows Server 2003, your hardware, and your applications.

note

Microsoft developed the Application Compatibility Toolkit to help users determine which applications in their environments support Windows Server 2003. You can obtain the associated whitepaper and download the utility from the Microsoft Web site at www.microsoft.com/windowsserver2003/compatible/appcompat.mspx.

Project Plan

The planning process for a project of this scope is a critical piece in its success. Make sure you take the following steps before embarking on the project:

• Establish functional teams with experts in directory services; administration and management; and core OS, networking, applications, and hardware compatibility.
  
  
• Have teams evaluate Windows Server 2003. Plan on four to six months to correctly plan your upgrade strategy, make clear assignments, and verify progress along the way.
  
  
• 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.
  
  
• Ensure that WINS is on your system until all clients are Active Directory (AD) aware.
  
  
• Identify the resource domains to be collapsed into the AD 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.
  
  

Upgrade Paths

It's also important that you understand the Microsoft supported upgrade paths for Windows Server 2003, as listed in Table 7.10.

Table 7.10. Supported Upgrade Paths to Windows Server 2003

Current Server OS	Upgraded Server OS
Windows 2000 Server	Windows Server 2003, Standard Edition
Windows 2000 Advanced Server	Windows Server 2003, Enterprise Edition
Windows 2000 Datacenter Server	Windows Server 2003, Datacenter Edition
Windows NT 4.0 Server	Windows Server 2003, Standard Edition
Windows NT 4.0 Enterprise Server	Windows Server 2003, Enterprise Edition

After you decide where you are, how you got there, and what is available, determine where you want to be and how to get there by asking these questions:

• 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?

After you know the answers to all these questions, 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 Web site on a regular basis for new information. HP Services can help you plan your upgrade to Windows Server 2003.

Decide the Correct Path for System Migration

Reasons to upgrade or to perform a new installation and other useful planning resources are available at the following areas of the Microsoft Web site:

• For existing Windows 2000 environments : http://www.microsoft.com/windowsserver2003/evaluation/whyupgrade/win2k/w2ktows03-2.mspx .

• For existing Windows NT 4.0 environments : http://www.microsoft.com/windowsserver2003/evaluation/whyupgrade/nt4/default.mspx .

Preparing for the Upgrade

To prepare for a successful upgrade, ensure that your server meets the system configuration and supported platform requirements and that you have all of the software and tools necessary to complete the tasks at hand. The following sections provide guidelines to help prepare you for this endeavor.

Supported Configurations

Windows Server 2003 should load and run on any ProLiant server that meets the recommended hardware configuration established by Microsoft. Carefully review the recommended system configuration and possible issues you might encounter. Performing due diligence optimizes your resources and testing scenarios.

ProLiant Installation and Upgrade Checklist

Before you begin the upgrade, ensure that you have access to the support software and other tools detailed in Table 7.11.
