I don't know the exact answer to your problem, but a while back I had a similar problem and I ended up writing a script that converted the DB to a flat file (using the old DB module) and then I wrote a script that converted the flat file back to a DB using the new modules (I believe I ran the first part at home and then uploaded the flat files to my website and then ran the conversion to the new DB there). It's at least a workaround. _______________________________________________ ActivePerl mailing list ActivePerl@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
