So we have a live website(ver. 3.9) with customer activity that we would like to transfer to a new upgraded Version that we have in development that is version 4.50.2 when we are finished with our customizations. We would like to transfer all the activity that occurred on the old live website since the start of the upgrade and development of the newly upgraded nopcommerce website. What would be the proper approach for all the sales information and new customer data. I notice that there is an export utility for orders and customers but there is no import utility for that data.
Thanks!
