I have several .mdb's & .gdb's generated form ArcGIS of various iterations from 9.3 to 10.3. Although ArcGIS Pro may see some of theses gdb's it doesn't recognize that which is contained within, meaning ArcGIS Pro "thinks" the gdb's are empty. As for the mdb's ArcGIS Pro doesn't see them at all. Both gdb's and mdb's are recognized in my ArcGIS Desktop 10.0 and are functional. Any insight?
