After all pools are deactivated and all Edge Servers have been uninstalled, run the Topology Builder Merge wizard to remove the BackCompatSite.

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.

To remove BackCompat site from 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 Download topology from existing deployment, and then click OK.

  4. In the Save Topology As dialog box, select the Topology Builder file you want to use, and then click Save.

  5. In the Actions pane, click Merge 2007 or 2007 R2 Topology.

  6. Click Next to continue.

  7. On the Specify Legacy Edge page, ensure that list of Edge Servers is empty. If the list is not empty, use the Remove button to remove all the legacy Edge Servers, and then click Next.

  8. On the Specify Internal SIP port setting page, click Next.

    On the Invoke Merge page you may see the following warning:

  10. Ignore the preceding warning, and then click Finish.

  11. In the Status column, verify that the value is Success, and then click Finish.

  12. In the left pane of Topology Builder, expand the BackCompatSite and ensure no servers are listed.

  13. Right-click the BackCompatSite, and then click Delete.

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

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

    The Publishing wizard will fail if any voice routes to the legacy Office Communications Server 2007 Mediation Server exist. For details, see Change Voice Routes to use the new Lync Server 2010 Mediation Server (Office Communications Server 2007 Migration).
