  • Decommission your legacy deployment, including Communicator Web Access, and then redeploy Office Communicator Web Access (2007 release).

  • Use Topology Builder to merge and publish your topology.

  • Test the deployment by starting Communicator Web Access and trying to use the internal URL.

To decommission and redeploy Communicator Web Access

  1. When you decommission your Office Communications Server 2007 pools, also decommission Communicator Web Access. For details, see
