Technically, yes you can (for example) copy the files from
C:\Users\<login name>\AppData\Local\WAI\PC-DMIS\2015.0 to
C:\Users\<login name>\AppData\Local\Hexagon\PC-DMIS\2016.0 but it is definitely not recommended. For one thing, you will miss new menu items, and there are quite a lot of bug reports solved by removing those configuration files and starting from scratch again (=
Reset User in Settings Editor).
