Transferring games between Switch consoles depends on whether they’re physical or digital. For physical games: Simply remove the cartridge from the old console and insert it into the new one—save data can be transferred via cloud (Switch Online) or wireless transfer. For digital games: On the new console, link the Nintendo Account that purchased the game. Go to 'System Settings' > 'User' > 'Add User' and sign in. Open the eShop, go to 'Redownload' to install the game for free. Transfer save data: Use wireless transfer (old console: 'Data Management' > 'Transfer Your Save Data' > 'Send'; new console: 'Receive') or download from the cloud (Switch Online subscribers). For 'Animal Crossing: New Horizons', use the Island Transfer Tool from the eShop to move your island. Note: Digital games are tied to the Nintendo Account, not the console, so you can redownload them on any console linked to the account.
