use dts/export wizard to extract data into sql. Try for 1 main table initially. if this is working fine.. then implement the similiar method for all the tables.
On top of it, the sql data type will not work in access db. How have you handled for the same ?
For e.g:- for currency in sql u would have used either money / smallmoney
But in access it is possible to use only by means of currency...
