You receive the following error when trying to publish your new Lync Topology, after removing the last Lync 2010 Front End Server.
ConferencingPoolInUse: The new topology XML removes services that will orphan existing conference directories.
Error: Cannot publish topology changes. Conference directories still exist on a pool that would be deleted. Remove the conference directories before continuing.

Error: An error occurred: "System.InvalidOperationException" "Cannot publish topology changes. Conference directories still exist on a pool that would be deleted. Remove the conference directories before continuing."
On one of your front end lync servers, open up the Lync Server Management Shell as an Administrator. Once open, execute the following command:
For each of the items that have a ServiceID referencing the Front End server you are trying to retire, execute the following command (replacing the appropriate values with the output found from the previous command):
Move-CsConferenceDirectory -Identity X -TargetPool poolorfrontendserver.mydomain.local
After all conferences have been moved off of your Lync 2010 Front End server, you should be able to successfully publish the topology.
Thanks solved my problem
This worked for me with one thing that wasn't totally clear. I had to run this from the Lync 2013 FE. when I first tried it from the 2010 server I was removing, it failed. Great Solution! thank you!
