OK, I lied. I had one problem upgrading, sent the file off to Autodesk, and they upgraded it for me.
I've found that keeping multiple versions around causes a lot of confusion. People have to keep track of which project is in which version.
Inevitably, someone will end up either wasting time trying to cancel out of an accidental upgrade, of opening an old Local file & working for an hour before getting the message that their Local is not longer compatible.
