Thank you all for your informative replies, and your recommendations.
It seems that the only reasonable solution is to rebuild, and of
course, that's the option that seemed most logical -- but I suppose
I was looking for a shortcut.

I so appreciate the voice(s) of experience shared in MMD, especially
those in areas beyond my knowledge.  Thanks to all for taking time
to answer!
