How to Transfer Demo Save Data on Nintendo Switch or Switch 2

Digimon Story Time Stranger supports carrying the demo's opening-chapter save data into the full game on Nintendo Switch and Nintendo Switch 2.

Keep the demo save on your system until the transfer has finished successfully. Nintendo specifically warns players not to delete the demo data when another transfer attempt may still be needed.

Note: Progress from Central Town - Adventure Trial does not transfer. Only the transferable demo story data can continue into the full version.

The most important restriction is that Nintendo Switch and Nintendo Switch 2 are treated as separate game versions for demo transfer.

• Nintendo Switch demo to Nintendo Switch full version: supported
• Nintendo Switch 2 demo to Nintendo Switch 2 full version: supported
• Nintendo Switch demo to Nintendo Switch 2 full version: not supported
• Nintendo Switch 2 demo to Nintendo Switch full version: not supported

You can compare the two official listings on the Nintendo Switch product page and the Nintendo Switch 2 product page.

If you already launched the full version without installing its latest update, Nintendo says you can still transfer the demo data after updating.

There is one important risk: if the full game already contains save data when you import the demo save, that full-version save will be overwritten by the transferred demo data.

Before approving the transfer, decide which progress you want to keep.

Nintendo specifically documents the No choice on the confirmation screen. If you select No, the transfer screen will not normally be displayed again on later startups.

If you change your mind, Nintendo says another opportunity can appear if you delete the full-version save and restart the game while the demo data is still available.

Note: Deleting full-version save data is destructive. Only use this recovery route when you are certain the existing full-game progress is not the data you want to keep.

There is a separate save-data rule that can be confusing. Bandai Namco confirms that save data belonging to the Nintendo Switch version can be transferred between a Nintendo Switch console and a Nintendo Switch 2 console after the appropriate update.

That does not convert the save into Nintendo Switch 2 software data. The separately sold Nintendo Switch 2 version remains incompatible with Nintendo Switch version saves.

The official Nintendo Switch and Switch 2 specifications page illustrates this distinction between moving Nintendo Switch software data between consoles and trying to move it into the separate Nintendo Switch 2 software version.

• Confirm that the full game has its latest update installed.
• Confirm that the demo save still exists.
• Confirm that the demo and full game are the same software version.
• Do not expect a Nintendo Switch demo save to appear inside the Nintendo Switch 2 version.
• If you previously selected No, remember that Nintendo says the prompt normally will not appear again unless the full-version save is deleted and the game is restarted.
• Do not look for Central Town - Adventure Trial progress in the full game because that portion is explicitly excluded from transfer.
