Digimon Story Time Stranger Demo Save Transfer Guide

Direct answer: progress from the demo's opening chapter can transfer into the full game, but the transfer is limited to the same platform. The Central Town – Adventure Trial progress unlocked after completing the demo does not transfer.

Steam's official demo page also warns that transferring demo data after an update can overwrite existing full-version save data in a specific situation, so players should read the transfer prompt carefully.

What transfers to the full game

The demo includes the opening chapter of Digimon Story: Time Stranger. Official Bandai Namco and Steam descriptions say save data from that opening chapter can carry over to the full version.

This provides a clean path for players who want to start before purchasing the full game without replaying the opening chapter on the same platform.

What does not transfer

After finishing the demo, players can access Central Town – Adventure Trial and explore selected areas and dungeons of the Digital World: Iliad. Steam explicitly states that this Adventure Trial data cannot be transferred to the full game.

Do not assume every item, action or exploration result from that post-demo trial becomes part of the imported full-game save.

Same-platform restriction

The Steam demo page says game data can only be transferred between copies of the game on the same platform. This means the existence of a demo on more than one platform does not itself imply cross-platform demo migration.

Important overwrite warning

Steam notes that if the full game is started without the latest update, demo data can still be transferred after updating. However, if full-version save data already exists at that time, the demo transfer can overwrite the full-version save.

Because this is an official warning, players with an existing full-game save should stop and confirm the transfer prompt rather than assuming the operation will merge progress.

Demo and full-game differences

The official demo page says there may be differences between the content and features in the demo and the full game. Treat the demo as a preview of the opening flow, not a permanent reference build for every menu or balance detail.
