Can't if my switch is banned ;-)Not sure you can move the actual save since there are different game ID and content in-game is slightly different, but you can always trade pokemon over.
Maybe only save is locking content on other game, so if we will transfer Sword save to Shield, we would get Sword content on Shield?The reason I said you probably can't use the data due to the event flags in the games, and the way the gym leaders are setup, you can probably transfer the save but your game would probably be incorrect since you are using data from Sword.
