superyetkin, sorry i closed that last project and it won't let me write to you, so i opened this one so we can talk further.
I want a system built that can import a shopping cart database from oscommerce 2.2, oscommerce max, cre loaded or zen cart.
This same system should be able to then export the imported data to any one of those carts. So a good understanding of the relevant database schemas and their differeces will be important.
So the end result would be that i could import from any one of them, and then export to any one of them.
The script should allow the end user to import the save, or import, save then export. It also should allow an end user to come back and select a saved import session and export that.
This script is to sit on a remote server, both the cart for import and for export will be on other servers, you must do testing to make sure this all works fine.
While the script is importing and/or exporting, it must give some meaningful feedback during this process.
