So we are in the early stages of testing Revit server for potential deployment between our ATL and DC offices. Virtually all our projects are in revit 2014 (with no plans to upgrade until 2016 releases). And we have been told that Revit Server 2015 will support 2015 and older (2014) file versions. However, I can't find anything to support this. Should we be running Server 2014 with Revit 2014 and Server 2015 with Revit 2014?
