I’m looking to Merge our Shop A into our Shop B. Same product line - just Shop B is better experience. I’m going to redirect Shop A to Shop B - but I want all customers from Shop A to have their order history in Shop B. How can that be done?
There’s at least 1 caveat - customers will need to be invited to create an account again because passwords don’t get transferred (this is irrelevant if you don’t use account logins for them).
I would test it on 1 customer first to make sure it lines up with what you’re looking for.
You can use Exportier - Data Export for this. You will be able to export all the needed fields from Shop A Customers and Orders in CSV and import to Shop B the relevant fields.
