Migrate Mediation Server

Lync Server 2010
 

Topic Last Modified: 2012-02-14

Your Mediation Server is merged into your Lync Server 2010 pilot topology when you run the Merge wizard. You configure the Lync Server 2010 Mediation Server, however, after all users are migrated because an Office Communications Server 2007 R2 pool cannot communicate with a Lync Server 2010 Mediation Server.

During the side-by-side migration, the Lync Server 2010 pool communicates with the Office Communications Server 2007 R2 Mediation Server, as illustrated in the following figure.

Users homed on the Office Communications Server 2007 R2 pool use the Office Communications Server 2007 R2 Mediation Server and PSTN gateway for outbound calls.

You can switch off the Office Communications Server 2007 R2 routes and Mediation Servers when all users are migrated and there are no more outbound calls from users homed on the Office Communications Server 2007 R2 pool.

When you configure your Lync Server 2010 Mediation Server, you must also upgrade or replace your Office Communications Server 2007 R2 gateways. Office Communications Server 2007 R2 gateways do not support Lync Server 2010 Mediation Server. You need to deploy gateways that are certified for Lync Server 2010 and associate them with the Lync Server 2010 Mediation Server. For details about deploying gateways, see Define a Peer of the Mediation Server for a Site in the Deployment documentation. This step is required before you can completely decommission your Office Communications Server 2007 R2 deployment.

The topics in this section describe configuration tasks that you need to perform after you have completed your migration of Lync Server 2010 Mediation Server. Transitioning the collocated Mediation Server to a stand-alone Mediation Server is an optional task.
