I would prefer you didn't. If you supply instructions then that implies
an implicit acceptance in the practice. I believe we should continue to
have a hardline stance that we do not support modification of the
database from under the GnuCash API. More below..

We do not support modifications to the database from outside the GnuCash
API. The reasoning is that we have a bunch of data constraints that are
not encoded in the database (and indeed cannot be encoded in the
database). For example, how do you encode that all transactions must be
balanced? Or that the parent of an account must have an appropriate
account type?
While it *is* possible to modify the data directly (this is a computer,
afterall -- the data is there), we neither recommend nor support doing
so, because it's quite possible to make your data unreadable, or worse,
readable with subtle errors.
I hope this answers your question, even if it isn't what you wanted to
hear.
Now, you COULD write a scheme or python script (or a C program) to make
the changes for you.... This would allow you to use the GnuCash API and
not violate the constraints.
Another thing: if you want to move *all* the entries from one account
to another then just delete the account and GnuCash will ask you where
you want to move them.
Good Luck,
