I have several ERD diagrams that I have been maintaining in Visio for several versions. They are not real big but would represent more effort than I want to invest if I had to recreate them from scratch. The potential of making typos is pretty high.
Visio 2013 doesn't support editing these documents. Is there a way I can convert the Visio 2010 version of the ERD to something that Visio 2013 will allow me to edit?
