Question: Microsoft recommends to do federation flip after all users are migrated since according the doc it will be a limited functionality for legacy users in case federation traffic is routed via Lync. What kind of limitations?

Answer: The limitations are always around what was supported in the OCS federation capabilities compared to what Lync 2010 supports. There are new capabilities in Lync federation abilities with other organizations.
