Import OSC Orders to Magento and Sort Customers into Groups

This is a two part data import and sorting project. The first part is importing all orders from an OSCommerce database into an existing and live Magento store. This includes mapping the OSC order statuses to specific Magento statuses. The imported orders must exist in Magento as standard orders in Magentos order tables. See attached for details and exceptions. Part two is to then sort all customers based on specific criteria into customer groups. This is based on billing country and payment history (as designated by order status). Full details are included in attached documents.
