I have a website that is based on nopCommerce 1.4 version.
When i was working on this website, i did 2 changes:
1st Change) In database I added 1 extra table in it that includes 3 extra fields for product information (Cost, MSRP, Bar Code)
So, along with it i added 3 stored procedures also (for addition/updation/deletion).
2nd Change) I also added one more store procedure to search option, in order to provide feature to search products with bar code number.
These are the only changes i did, now i have many registered customers on the website. What's the best procedure to upgrade from 1.4 to 1.8 without losing any data , products information , images and customers registrations ?
Andrei, could you please guide me in a right direction ?
