[Switch] When I select "Transfer Your User Data", error code 2124-0290 is displayed. What should I do?A
This error code is shown after selecting "Transfer Your User Data" when you log in to a Nintendo Account for which transfers are not possible.(* 1)
(* 1 The error is displayed upon logging in to a Nintendo Account on the destination console that has never been linked to your Nintendo Switch (user account).)
In order to transfer your user data, first check the Nintendo Account that's linked to the user on the source console.
After you've confirmed the account, start the user transfer process again. When you reach the Nintendo Account login, make sure you log in to the Nintendo Account that's linked to the user you're transferring.
