I'm not aware of a utility that can figure out for each item whether all of the pieces (figures, poses, materials etc...) have been transferred from one runtime to another.
I have in the past manually moved things from one runtime to another, but it didn't work flawlessly.
The best way I found is to create a few new, more organized runtimes and start reinstalling  content - as needed.
