Thanks Jim, as always, great advice.

I can report that I got impatient and since the vm didn't have
anything really that serious on it... (I would rather not lose some of
it of course) I took the gamble.

Once I looked at how simple the xml files really were, I just edited
the new ones to suite. 

One thing I did run into was a problem virtual disc... once it came up I
remembered vaguely seeing similar errors before the big changeover

It involved a specific disc being reported off line when in fact it
was where it was being reported not to be.  

I still don't know why that is, but I finally remembered some name
changing in previous setup where I'd inadvertently created a disc with
an odd name compared to the others.

When renaming it, that brought errors, so I finally just made a new
disc with the name I wanted.. and just left the old one there.  So it
isn't actually a problem.  I can just delete it at some point when I'm
really sure there is nothing on it that has not been duplicated onto a
new disc.

Since the vm was in a 'saved' status instead of a closed status when
the crash occurred, it was reporting on the basis of the saved state.
Fortunately it still allowed me to start the vm OS and so I ran it,
checked things out then formally closed it, deleting the disc in
question.... all good now.

I've closed and restarted a couple times now and it comes up with no
errors reported.

Fortunately for me  there were not the kind of changes between
versions that would cause a big mess.... I should have looked at the
changes for the new version, at least, but did not even do that.

Got away lucky this time....
