If a Lync Server 2010 Front End pool is hosting call admission control (CAC), you must move CAC hosting to a Lync Server 2013 pool before you can remove the Lync Server 2010 Front End pool.

To reset CAC

  1. Open Topology Builder.

  2. Right-click the site node, and then click Edit Properties.

  3. Under Call Admission Control setting, make sure Enable Call Admission Control is selected.

  4. Under Front End pool to run call admission control (CAC), select the Lync Server 2013 pool that is to host CAC, and then click OK.

  5. Publish the topology.
