Part 3: Windows Server 2003 Upgrades and Migrations Microsoft Windows Server 2003 Inside Out Chapter 9 Movetree is used to do the following: . Move security principals to a new domain and delete them from the source domain . Migrate user passwords Normally, you should use ADMT to migrate users, computers, and groups; use Movetree to move directory objects that are not migrated by ADMT (such as members of default groups such as Administrators or Domain Admins). Third-Party Migration Tools Independent vendors produce migration tools that provide much of the same functionality as the Microsoft tools. Each product is different, however, and the features and benefits of each must be evaluated in the context of your migration environment and process. Following are two third-party tools: . Quest Fastlane Migrator http://www.quest.com/migrator/ . Aelita Enterprise Directory Manager http://www.aelita.com General Considerations for Migrations Consider your source and destination (target) domains involved in the migration. The target domain must be an Active Directory domain running in Native mode (either Windows 2000 or Windows Server 2003). When evaluating your migration scenario, you must determine which types of migration you can do. There are two types of migrations: . Interforest migrations Migrating from a Windows NT domain or a different Active Directory forest. . Intraforest migrations Migrating from an Active Directory domain within the current forest. Intraforest migration can also be used to consolidate multiple Active Directory domains into a single domain, easing management of users and groups under a single set of policies. You must establish trust relationships between the destination domain and all domains trusted by the source domain (use the Trust Migration Wizard to assess and implement domain trusts for migration). To be migrated, the source objects must be security principals users, security groups (including Windows NT 4 local groups, domain local groups, and global groups), or computer accounts. Any account (or other source object) that has a SID that already exists in the destination domain or forest cannot be migrated. For example, irrespective of the domain of origin, built-in accounts such as Administrators and Power Users cannot be migrated because they use identical SIDs. 254
