Transporter

Not the best one, but it's free - gets the job done. Sometimes throws internal error and you have to try again and again. If it's fault of the serialization then it's gonna outline it.

This app is garbage. Doesn't even work when exporting/importing from other instances of Shopify. Unacceptable as a tool they offer to enterprise level users.

My God, I hate this app. We are splitting our existing Shopify store and needed to migrate some orders over to the new Shopify store. Despite Shopify recommending this app, the export from Shopify does not match the import csv. The app rejects orders for several reasons, even though these are historic orders and it does not matter that the information might be incorrect. 1. Rejects invalid emails
2. Rejects phone numbers that are not in E.164 format (i.e. around 90% of orders)
3. Date must be in ISO 8061 format (have to convert every single date)
4. Despite the Shopify export using 'unfulfilled' as a status, this is not a recognised status for Transporter and it must be blank in the import csv It takes so long to rectify these above issues, when all we want to do is use the order data and just reimport it back into Shopify.
