Move Active Directory Roles
In this task, Windows EBS moves the domain naming master role and the primary domain controller role for Active Directory Domain Services to the Management Server. You must transfer the roles within 30 days to maintain compliance with the licensing terms.
To move Active Directory roles to the Management Server
In the Configuration and Migration Tasks checklist, click Move Active Directory roles, and then click Move Active Directory roles. The role-transfer process begins.
A confirmation dialog box appears when the roles are moved to the Management Server. Click Close.
Replication of this change to all domain controllers in your network may take up to two hours. Do not perform domain-level operations until the replication has completed.
