Virtuemart product categories from database

We need a person who can find and export from old database and then import to the new database virtuemart products with connected categories. 1. We don't need to import complete database because we have make so many changes 2. we need to import just the line where the products are with connected desired category 3. on this new database from some reason we can't add categories to the product (after the save nothing happens....) and some lines are missing. we have make so many changes in the last 2 weeks on site so this is problem to reupload the database.
