Active Directory Migration Tool version 3.1

Brief Description

The Active Directory Migration Tool version 3.1 (ADMT v3.1) provides an integrated toolset to facilitate migration and restructuring tasks in an Active Directory Domain Services infrastructure.

Overview

The Active Directory Migration Tool version 3.1 (ADMT v3.1) simplifies the process of migrating objects and restructuring tasks in an Active Directory® Domain Service (AD DS) environment. You can use ADMT v3.1 to migrate users, groups, and computers between AD DS domains in different forests (inter-forest migration) or between AD DS domains in the same forest (intra-forest migration). ADMT can also perform security translation (to migrate local user profiles) when performing inter-forest migrations.
