Besides what Jon says above (he knows a lot more that I do...lol...) I have a list of things I do. I'll post it in case it helps someone but beware, it has my personal configuration for a lot of items that you may not want. So, pick and choose the more "global" things here.
I find that merging the '3dsmax.ini' gets me the farthest. Some developers might cringe at me doing that but so far it has not caused me any problems.
Again, just use my list as a guide and reference but not as a bible. However, I use my list myself each year and in about 20-minutes I'm back to about 95% of where I was. I hope that Autodesk provides us with a "Migrate" button one day that does it all.
