windows 2000 migration strategy

Migration from Windows NT 4.0 to Windows 2000 Active Directory can be achieved by upgrade or restructure.

Microsoft has provided an easy, low-risk migration path in the form of domain upgrade. Many customers will find that this answers all of their migration requirements. Microsoft has listened to customer feedback and is also committed to providing great tools to support domain restructure, either as part of the initial migration, or post-migration to support corporate operations such as acquisition and divestiture. The Microsoft migration tool and the basic utilities represent the first step.

Microsoft tools and utilities represent only part of the story. Many customers will have strong working relationships with ISV tool vendors in this area, and will want to continue using tools they are familiar with. Microsoft has been working with ISVs to ensure that their domain restructuring tools are able to make use of features such as SIDhistory and cloning operations.
