Animal Crossing: New Horizons will let you move users and save data to another Switch “later this year”
Nintendo’s UK website provides some information regarding Animal Crossing: New Horizons save file transfers. Although it won’t be supported at launch, a function is coming “later this year” that will let players move users and save data to another Switch.
That’s not the only save-related feature due out after launch. Nintendo Switch Online cloud saves aren’t supported, though there are plans to let players recover data in the event that your system gets lost or damaged. However, it will only be possible to recover data one time.
