i am in the middle of upgrading to the latest version but i am not keeping all of the modules i have installed on my previous version, all i am really interested in keeping is customers and products and anything with involved past orders and history etc because i starting from scratch seeing as most of the modules i do need to keep have ewer versions specific to 1.3.9, can someone please tell me which specific parts of the database i needs as when i imported my customers and products i had no order history show up so i think im missing something?
