We have migrated customers and orders data from M1 (220.127.116.11 EE) to M2 (2.3.1 commerce) successfully But when we are doing testing at the admin end for the orders found that the Reorder button was missing. Then we checked below scenarios
Reorder settings enabled (System -> Configuration -> Sales -> Sales -> Reorder)
Crated an order in the frontend then it is showing reorder at admin end.
Can anyone have faced this kind of issue could you please advise.
