Happens every year. Upgrade and spend half a day or more trying to get everything back to the way I had it. All I have is a couple small toolbars for commands that are several clicks deep in the ribbons and I want them "right there" all the time.
I thought Autodesk 360 might be a good tool for this. All it did was DOWNLOAD some old settings and destroy one of the toolbars I'd created. They really need an override in there to specify upload, download, overwrite or don't.
Anyway, I'm trying to migrate (I guess that's the technical term) my settings from 2013 Mechanical to 2014 Mechanical. It's probably too late already, after 360 did its deal, but I really want to get this down so we don't go through it every year anymore.
I maintain that PTC had this part of it down Pro/ENGINEER. You had a config file that was editable plain text.
