Ken,
My experience is that making a big leap is not an issue with panels, unless custom items are out of place.
The problems are in the base JMRI directory, such as C:\Users\<username>\JMRI. ?There have been a lot of changes in profile handling since they were introduced in JMRI 3.8. ?
I have helped two local layouts upgrade from 3.10 to 5.x. ?The JMRI data directory is renamed. ?After removing and installing Java and JMRI, PanelPro is started which creates the default My JMRI Railroad profile. ?For these layouts, the roster directory and the layout data xml file are copied from the old directory. ?After rebuilding the roster index, the data flle is loaded and stored. ?

I’ve got a feeling the biggest issue with getting up to date on your layout is many things were put in directories that conflict with newer versions. In short, everything for your layout should be in the JMRI directory in the home directory of the login user. At the least, that’s the connection information and the panel file. But long time ago, many users put custom icons and similar things into the JMRI directory under the \Program Files\ path.

Does this sound like a description that fits?
