        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.
