[GNC] Transferring data from one set of books to another

[Rich Shepard]

I have two sets of books: business and personal; still running gnucash-3.11
on my Slackware64-14.2 desktop; it does all I need it to do. I updated my
customer list in the personal book rather than the busienss book by mistake.
Is there a way for me to transform those data from person to business
without having to manually re-keyboard all of them?

TIA,

Rich
