If you have moved all your users to Office Communications Server 2007 R2 pools, you will now remove the existing Office Communications Server 2007 Edge Servers. Ensure that you have access to the existing certificates so that you can install them on the new Edge Server.

Note:
After you deactivate the existing Edge Servers, external users will have no access to Office Communications Server until you have deployed the new Edge Server.

For details about deactivating and removing Office Communications Server 2007 Edge Servers, see Starting and Stopping Services and Deactivating Server Rolesin the Administering Office Communications Server 2007 R2 documentation.
