ProjektActive Directory Migration

 

Microsoft Active Directory Migration Tool (ADMT)

ADMT has been developed by Microsoft and can be downloaded for free. You can find the link at the end of this page. The current version of ADMT is 3.2 and must be installed on a Windows Server 2008 R2+. Please prepare an SQL instance before the installation. All necessary information is stored there.

ADMT in version 3.2 supports the following Active Directory Domain Modes:

  • AD Domain mode 2003
  • AD Domain mode 2008 and 2008 R2
  • AD Domain mode 2012 and 2012 R2


User, groups, computer objects and permissions can be migrated to Windows systems with ADMT. By installing the tool PasswordExportService you can also migrate the passwords of the user objects. Active Directory Migration Tool supports the SID history migration, so that users can still access a variety of resources, without requiring them to be additionally authorized to the migrated account.

Data or permissions from applications (such as Microsoft Exchange or SQL Server) can not be migrated with ADMT .

 

Dell/Quest Migration Manager for Active Directory

QMM is licensed per managed user. The link to the manufacturer's product page can be found at the end of this article.

With QMM you can migrate users, groups, computer accounts, organizational units, sites, and trusts. QMM also supports the SID history migration, so that users can continuously access a variety of resources, without additionally authorize them to the migrated account.

QMM has some features that ADMT does not have. You can set up a directory synchronization so that changes in AD objects are automatically synchronized in the other environment. This is really helpful for big migrations projects, which run over a longer period. In addition, Quest offers more opportunities to organize resource migrations.

The following applications are supported with the appropriate license of QMM:

  • Exchange mailboxes (mailbox contents, permissions and Outlook profile updates)
  • SQL databases (permissions)
  • SCCM (permissions)
  • IIS (permissions)
  • Agentless updates for example, NAS filers
