The Mediation Server exists in two forms: the stand-alone Mediation Server, and the basic hybrid gateway. In both cases, the management of the Mediation Server role is the same.

In certain situations (for example, when you experience a hardware failure or network reconfiguration), you need to replace one Mediation Server with another Mediation Server. The focus of this document is on replacing the Mediation Server (that is, either a stand-alone or a gateway device) with a stand-alone Mediation Server. This document does not cover how to size or replace the media gateway device. For details, see Enterprise Voice Server-Side Componentsin the Planning and Architecture documentation.

This document is targeted at IT Professionals who have a thorough understanding of Microsoft server technologies, networking technologies, and complex Active Directory topologies.
