Another follow up ... a catch 22 ...
If the questions in the original course had images (graphics), those images might be restored to the moodle file system but they could be orphaned ... not associated with anything.
There is yet another option if all you want is the files uploaded to that course. One could extract the files and save them as humanly recognizable names to upload to a new course in new version.
Have a script for that if interested ... command line only ... mac or Linux only.
Nothing is perfect! :|
