[AccessD] How to copy and convert a db to a previous version?

Hi all,

I have an application under Access 2007.

There is a back end and a front end.

It is needed to make a copy of the back end, but this copy must be in a mdb
format, not accdb.

I need to have a button on the front end to do that automatically: make a
copy of the back end and  convert it to Access2003.

I'm looking for a docmd or runcommand that could do that in one shot! but
with no success.

Do you know if there is such a command?

Best regards,

Philippe Pons
