On the Switch 2 game save data lives in system memory whether the game is on a card or downloaded, and it cannot be copied to a microSD Express card, so the only copies are Save Data Cloud (for Nintendo Switch Online members and supported games) and a system transfer. A transfer from an old Switch or Switch 2 can go through Nintendo's servers, which initializes the source console, or by local communication, which copies Save Data Cloud-supported saves and deletes the rest from the source. A factory restore deletes everything in console memory, and Recovery Mode can restore without deleting save data.

How to confirm Nintendo says saves for unlinked users and unsupported games are deleted from the source after a local transfer
- 3
A different user account
What separates it The game starts without progress on a new user
How to confirm Save data is tied to the user account; select the same user, or back up and restore for that account
- 4
A game without Save Data Cloud support
What separates it A message says the software doesn't support cloud backup
How to confirm Check the game's eShop page; unsupported games cannot be backed up to the cloud
- 5
Deleted software mistaken for lost save data
What separates it The game icon is gone but progress may exist

Before you touch a setting
Record this first — changing settings destroys the evidence
- The game and the user it belongs to
- Whether a Nintendo Switch Online membership and a backup exist
- Whether a system transfer or reset happened and which method
- Whether the source console was a Switch or a Switch 2
Try in this order
0 of 8 completedUnderstand where saves live
ReversibleNintendo says game save data on the Switch 2 is stored in system memory, whether the game is downloaded or on a card, and cannot be copied to a microSD Express card.
Back up to Save Data Cloud
ReversibleWith a Nintendo Switch Online membership, highlight the game, press minus or plus, choose Save Data Cloud and Back Up Save Data, or use System Settings, Data Management, Save Data Cloud.
Choose a transfer method
ReversibleA system transfer moves data from a Switch or Switch 2 to a Switch 2 during initial setup. Uploading to a server initializes the source console; local communication copies Save Data Cloud-supported saves and deletes the rest from the source.
Prepare a Switch as the source
ReversibleNintendo recommends moving as much data as you can to system storage before a transfer from a Switch, and you may be asked to insert the microSD card temporarily to transfer screenshots and videos.
Check what is not transferred
ReversibleBluetooth audio devices and custom controller button mappings are not transferred; set them up again on the Switch 2.
Know what a factory restore does
ReversibleIt deletes all data in console memory including software data, save data, screenshots and user information. Linked Nintendo Accounts are unlinked, not deleted, and Save Data Cloud backups can be downloaded after you create a user and re-link.
Use Recovery Mode to keep saves
ReversibleTo restore without deleting save data, use Recovery Mode; it retains save data and user settings on the console.
Redownload deleted software
ReversibleRedownload deleted software, since deleting a game does not affect its save data, so redownload the software and resume.
Model-specific
What is true of this model and not of its siblings
- Storage
- 256GB of UFS storage with part reserved; game save data stays in system memory and cannot be saved to a microSD Express card.
- Transfer contents
- Digital software, users and settings, friends, play activity, screenshots and videos in system memory, registered devices, parental controls and Mii data transfer; Bluetooth audio settings and button mappings do not.
- Tools and supplies
- A Nintendo Switch Online membership, both consoles on the same network for local transfer and your account details.
- What to tell Nintendo
- Which transfer method you used and what is missing; a part number is not needed.
Stop boundary
When this stops being a self-service repair
- !If save data is missing and no backup exists, contact Nintendo before making further changes
- !If a transfer fails partway, do not initialize either console; contact Nintendo
- !If Save Data Cloud shows an error, note the message and contact Nintendo
