I have approx 3200 products which needs to be migrated from one magento website to another. All products are having hundreds of attributes and brands which also needs to be migrated. Moreover both the websites have their own orders and customers which needs to be as it is.
I tried with default export/import functionality but that throws errors for unknown attributes and brands. Also, I can’t directly change the database as website have it’s own customers and orders.
I am not able find a way to do this. Please help.
