The export format will likely be some flavour of CSV. IF you are
lucky, identical. If not, you could cook up a converter using

The key is to avoid the commit/rollback logic on each record.
This sticks in my mind from a RFP I was involved in to purchase a new
mainframe for my employer BC Hydro. We required a benchmark that at
one point involved a database load. The Univac (now Unisys people)
were inexperienced and did not realise this load problem.. The
database load took about 24 hours. The pro-IBM forces at BC Hydro
refused to let them have another shot at it, avoiding the
commit/rollback logic.
