Our license file tops out at 2015. They send us a new one only when we ask and we only ask when someone tries to open a 2009 project and the software can't get a license. Plus, I've been on assignment for nine months in a Bentley only world, so we have done nothing towards moving from 2013 to 2014 or 2015. Now that I'm back and we are upgrading a number of users PC's, I am looking for any advice on moving to 2014 or 2015. I seem to recall some posts where users mentioned staying in an older version as the bugs were getting in the way of production. I figured before jumping into 2015, I'd see if anyone know of any reasons to hold off at an earlier version.
