Part 3: Windows Server 2003 Upgrades and Migrations Migrating to Windows Server 2003 When migrating user accounts, user names are limited to 20 characters in length anything beyond 20 characters is ignored. Tip Null values in source domains do not overwrite values in the destination domain. Commonly, when you migrate from Windows NT Server 4, the network environment is structured into Windows NT account domains and Windows NT resource domains. During the migration process, the user and group information is copied from the account domains, and the service account and local group information is copied from the resource domains. All this information is integrated into the destination domain. When migrating from Windows NT, always migrate the account domains first and then the resource domains this will establish the user and group accounts prior to migrating resource permissions referencing those accounts. Determining the Approach to Migration You can use a variety of approaches when migrating the systems on your network. These approaches can be categorized as manual, scripted, automated, and user-driven. Manual Migration The manual migration approach uses USMT and includes the following steps: 1 Acquire the user state information (by using Scanstate.exe). 2 Deploy the new operating system. 3 Load the new operating system with the user state information (by using Loadstate.exe). Chapter 9 Tip Manual migration is Information Technology (IT) labor-intensive, doesn t scale, and has increased error potential. Scripted Migration Scripted migration requires that you write migration scripts to acquire and load user state information; yet, once written, the migration process involves the following steps: 1 Use scripts to acquire user state information. 2 Use the scripts for unattended installation of the new operating system. 3 Use the scripts to load user state information into the new operating system (requires you to log on as Administrator). Tip Although it still requires significant IT labor, scripting the migration can reduce error potential and speed migration.
