Speaking from a few decades experience in the cypher mines .............

What you do FIRST is make a COPY of the files you propose to merge. You 
try merging THOSE (and see the results). That way, if not satisfactory 
at least your original files haven't been disturbed and you are no worse 
off than when you started. The secret of experiencing fewer disasters is 
test, test, test, and whenever possible work in such a way that you can 
cleanly back out from any changes.

That of course isn't specifically GnuCash advice but general purpose advice.
