After you deploy Microsoft Lync Server 2010, a federation route for this site is not configured. In order to use the federated route being used by Microsoft Office Communications Server 2007, Lync Server 2010 must be configured to use this route.

To enable the Lync Server 2010 site to use the Director and Edge Server of the BackCompatSite, you must associate the legacy Edge pool by using Topology Builder.

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 details, see Delegate Setup Permissions in the Deployment documentation. For other configuration changes, only membership in the RTCUniversalServerAdmins group is required.

To associate the legacy Edge pool by using Topology Builder
  1. Log on to the computer where Topology Builder is installed as a member of the Domain Admins group and the RTCUniversalServerAdmins group.

  2. Start Topology Builder: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Topology Builder.

  3. Select your Lync Server 2010 site.

  4. On the Actions menu, click Edit Properties.

  5. Under Site Federation Route, select Enable, and then select the Office Communications Server 2007 Director listed.

    If you are not able to edit the Site federation route assignment setting, it means that you did not select an Edge Server when you ran the Topology Builder Merge wizard. To enable this setting, see step 6 of Merge Using Topology Builder Merge Wizard (Office Communications Server 2007 Migration).
  6. Click OK to close the Edit Properties page.

  7. In Topology Builder, navigate to the Standard Edition Server, right-click the pool, and then click Edit Properties.

  8. Under Associations, verify that the check box next to Associate Edge pool (for media components) is selected and that it points to the Lync Server 2010 Edge Server created earlier.

  9. Click OK to close the Edit Properties page.

  10. In Topology Builder, select the top-most node, Lync Server 2010.

  11. From the Actions pane, click Publish Topology, and then click Next.

  12. When the Publishing wizard completes, click Finish.

    The procedure just completed configured Lync Server 2010 to use the legacy Edge Server for federation and the Lync Server 2010 Edge Server for media traffic flow.
