As a reminder to all third-party public MWS developers, the due date for the first phase of migration for the MWS Merchant Fulfillment (MFN), Order, and Reports sections is July 31, 2022. Your organization may have received a message via email or in your Seller Central Case Log requesting you to complete a Migration Plan Form. If you have not already done so, please submit your responses as soon as possible.
