I am migrating from Exchange 2010 to 2013. We are not using Public Folders on 2010. When I try to remove the public folder database from 2010 it tells me that I still have replicas. I read throughh the guide on moving public folders from 2010 to 2013 and it looks like a pain. Since we aren't using the PF on 2010, do I even need to migrate them to 2013? 2010 has the system public folders still (oab, schedule + free busy).
