Use the procedure that follows to transition your Mediation Server that is collocated on a Standard Edition server or Front End pool to a stand-alone Mediation Server for a single-site deployment.

To successfully publish, enable, or disable a topology when adding or removing a server role, you should be logged on as a user who is a member of the RTCUniversalServerAdmins and Domain Admins groups. It is also possible to delegate the proper administrator rights and permissions for adding server roles. For details, see Delegate Setup Permissions in the Deployment documentation. For other configuration changes, only membership in the RTCUniversalServerAdmins group is required.
