In most cases, we handle the migration process between both you and the seller and this is usually mentioned in the listing.
After payment, our support team will ask you for hosting details, registrar, and monetization codes or User ID's if applicable. For Amazon FBA we will start the process of transferring over the listing to a new seller account or migrating the old owner's seller central account to the new owner. Once you provide the required information, we’ll begin the migration process on your behalf.
