Uh, I would save the order history, actually. When they merged the older intersango into the new intersango the transaction history seems to have gotten lost

Thanks very much. I took your advice. Just in case.
Currently the migration code does not contain your previous history.
I have a partial script for pulling user histories as a csv file, although it is very much not complete.
