Gary D,
A lot would depend on how many of the features of JMRI you are using? If you
are only using it for decoder programming, then the only real tripping point
is the layout connection details. It would likely be easier to set them
fresh, but you wouldn't have to make intermediary steps. But if you are
using panels and lots of scripts, then there are more issues to consider.
Biggest is a number of changes that effect homemade scripts. If you give
some details of what features you use, we can give better clues for you.
