The primary improvements in the Active Directory Migration Tool version 3.2 (ADMT v3.2) are compatibility between ADMT and current versions of Microsoft® Windows® operating systems. Specifically, you can install and run ADMT v3.2 on editions of the Windows Server® 2008 R2 operating system, which does not support installation of earlier versions of ADMT. In addition, you can use ADMT v3.2 to migrate managed service accounts, which are a new feature in Windows Server 2008 R2.

Note

Before you perform an in-place upgrade of a computer to Windows Server 2008 R2, remove any versions of ADMT. Otherwise, you cannot uninstall ADMT v3.1 by using Programs in Control Panel. If you did not uninstall ADMT v3.1 before you upgraded the computer, see Article 974625 in the Microsoft Knowledge Base (http://go.microsoft.com/fwlink/?LinkId=183260).

ADMT v3.2 setup detects earlier versions of ADMT that are installed. You must remove any prior versions of ADMT before you can finish installing ADMT v3.2.

In addition to compatibility, the following section describes other changes and improvements in ADMT v3.2.

SQL Server database installation changes

Before you can install ADMT v3.2, you must have Microsoft SQL Server® 2005 Express with Service Pack 3 (SP3), SQL Server 2008 Express with Service Pack 1 (SP1), or SQL Server 2005 or later installed, and you must have configured a database instance for ADMT to use. If you plan to run the ADMT v3.2 console locally on the computer that hosts SQL Server, you can use SQL Server Express. We recommend that you also install the latest service packs for SQL Server.

Managed Service Account Migration

ADMT v3.2 provides the Managed Service Account Migration Wizard and the admt managedserviceaccount command to migrate managed service accounts. You can explicitly specify managed service accounts that need to be migrated, or you can specify computer accounts that ADMT can query for.

Deprecated features

The following features that were available in previous versions of ADMT are not available in ADMT v3.2:

  • Support for migration to or from domains that have domain controllers that run Windows 2000 Server. If you want to use ADMT v3.2, both the source domain and the target domain must have a domain functional level of at least Windows Server 2003.

  • The Exchange 5.5 Mailbox Migration Wizard

  • The admtdb import command that allowed the import of an existing ADMT v2 database into an empty database
