I was involved in a recent Lync migration where a new Lync pool was deployed side-by-side with an OCS 2007 R2 pool. Several pilot users were moved to the new Lync pool and the OCS 2007 R2 edge server was still being used for external Lync and OCS user services.
Everything worked as planned except the Lync users on the new Lync pool were getting the infamous “Presence Unknown” for both Public IM (PIC) contacts and their Federated Contacts.
All the basics were checked – connectivity between the new Lync pool and the OCS 2007 R2 edge, certificates, etc…, and everything looked okay.
What solved the problem in the end was rebooting the OCS 2007 R2 edge server. After the OCS edge server was rebooted, all of the PIC and Federated contacts for the new Lync pool users started to work. I am not sure exactly what effect rebooting the edge had, but wanted to pass it along in case it helped someone else.

Hi,
Yes, you can use an OCS 2007 R2 Edge with your Lync front-end/pool. The supported method for upgrading from OCS 2007 R2 is to introduce your Lync Pool and configure it to use your existing OCS 2007 R2 Edge before bring up and cutting over to the new Lync Edge.
See the TechNet article Migration from Office Communications Server 2007 R2 to Lync Server 2010 for more information.
