Part 3: Windows Server 2003 Upgrades and Migrations Microsoft Windows Server 2003 Inside Out Chapter 8 Upgrade the PDC When you are ready to begin the upgrade process, start Windows Setup from a Windows NT 4 command line, and run Windows Server 2003 Setup (Winnt32) either from the product CD or from a network distribution folder. During the upgrade, Setup will run the Active Directory Installation Wizard, which performs the following tasks: . Prompts you to create a new forest or join an existing forest and to create a new domain tree or join an existing one . Establishes the directory datastore, Kerberos, which establishes parent child trust . Copies schema, configuration, and domain directory partitions from the parent domain . Copies security principals stored in the Security Account Manager (SAM) into the directory and converts groups as discussed previously by establishing corresponding accounts in Active Directory. User and global group accounts are put into the Active Directory Users container, computer accounts are put into the Computers container, and Windows NT 4 local groups are put in the Builtin container. These container objects (Users, Computers, and Builtin) are not organizational units (OUs) and are not subject to administrative changes (moving, deleting, renaming). Post-PDC Upgrade When the upgrade of the PDC has been completed, you can commence with upgrading the BDCs until all domain controllers are running Windows Server 2003. Tip A Windows NT 4 PDC that has been upgraded to Windows Server 2003 is able to continue to replicate security principal changes to Windows NT 4 BDCs. Once all domain controllers are upgraded (and replication has completed), proceed with upgrading member servers. Tip Upgrading Windows NT applications Prior to upgrading existing Windows NT applications, look at the Relnotes.htm file in the Docs folder of the Windows Server 2003 product CD. You can also test the compatibility of applications with Windows Server 2003 by using the Application Compatibility Toolkit (available at the Microsoft Web site at http://msdn.microsoft.com/compatibility). You can also use the Program Compatibility Wizard to test and enable compatibility settings that might allow applications to operate correctly. Some applications, such as disk management tools, developed for earlier versions of the Windows Server operating system will not work correctly even in compatible modes and could pose risks to the integrity of the installation. 250
