The process of migrating account objects from a source domain to a target domain in another Active Directory forest involves first migrating service accounts and then migrating global groups. After the groups are in place in the target domain, you can migrate users according to the process that you selected, either while using the security identifier (SID) history for resource access or without using SID history for resource access. When the account object migration process is complete, you can instruct users from the source domain to log on to the target domain. The following illustration shows the process for migrating accounts between domains in different forests.
