In a mixed environment, if you create a new trusted application server after merging the legacy Office Communications Server topology with Lync Server 2010, and you define a new trusted application server using Topology Builder, you must set the next hop pool to be a Lync Server 2010 pool. In a merged environment, both the legacy Office Communications Server pool and the Lync Server 2010 pool appear in the drop down list. Selecting the legacy pool is not supported.

To successfully publish, enable, or disable a topology when adding or removing a server role, you should be logged in 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 Lync Server 2010 Standard Edition server or Enterprise Edition server Deployment documentation. For other configuration changes, only membership in the RTCUniversalServerAdmins group is required.
