SUMMARY

The Migration Wizard in Microsoft Exchange 2000 Server Service Pack 1 (SP1) and in later versions of Exchange includes the ability to migrate user accounts and mailboxes from Microsoft Exchange Server 5.5 to a native-mode Microsoft Exchange Server 2003 organization or to a native-mode Exchange 2000 organization.

The table in the "More Information" section describes how accounts and mailboxes are created and mapped during migration. You can migrate accounts and mailboxes whether or not the Active Directory Connector (ADC) is installed. If the ADC is installed, it must be configured with inter-organizational connection agreements. The Exchange Migration Wizard is not designed for use in a single Exchange organization. Additionally, the ADC must be configured to create contacts in the Active Directory directory service.
