pyxmdb.py is a free tool to eXport or iMport data from/to a database. It is written in Python (v2.5 and v2.4) and is meant to be as database neutral as possible. Anything that is DBMS specific, is stored in a user editable config file (pyxmdb.py.cfg). 

If desired, you could use this to perform the 'E' and 'L' parts of an ETL (Extract, Transform, Load) process.   The 'T' could then be performed by any other application or utility of your choice.   This easiest way to do this, would be to have one copy of pyxmdb export the data to standard out, pipe the output to something like awk or sed, and then pipe that output to another copy of pyxmdb to import the data.

NOTE: My apologies for taking well over a year to get a new release out.   Both my personal and work lives got really busy, and even more complicated, than they already were.
