Switch Game Demos: What Carries Over to Full Game

Updated 7 November 2026 · Standard formula, shown below

When you play a Nintendo Switch game demo and later buy the full game, your save data and progress from the demo generally carry over, but there are important exceptions. This article explains what transfers, what doesn’t, and how to make sure you don’t lose your progress.

How Demos Work on Switch

Nintendo Switch demos are free, downloadable versions of full games, designed to let you try a limited portion before purchasing. They are listed on the Nintendo eShop, often under a “Demos” section, and each one has its own product page. When you download a demo, it appears as a separate icon on your home menu, distinct from the full game. The demo’s save data is stored separately from the full game’s save data, but many developers design the demo to write save data in a way that the full game can read.

The key factor is whether the demo and full game share the same title ID (a unique identifier for each software). If they share the same ID, save data is often compatible. If they have different IDs, the full game may not recognize the demo’s save, or it may require a special transfer process. Nintendo does not enforce a universal rule, so each publisher decides how to handle it.

What Usually Carries Over

In most cases, the following items carry over from a demo to the full game:

Save data: Your progress in the demo (e.g., completed levels, unlocked characters, collected items) is typically transferred if the game supports it.
Settings and preferences: Some games save control configurations, audio settings, or language choices in the save file, so those carry over too.
Purchased content (if any): Some demos allow in-app purchases (e.g., unlocking the full game or buying extra content). If you buy the full game, that purchase is tied to your Nintendo Account and will be available.

However, this is not guaranteed. Always check the demo’s eShop page or the game’s official website for a note about save data transfer. For example, Dragon Quest XI S: Echoes of an Elusive Age demo lets you transfer your save to the full game, and Octopath Traveler demo also supports transfer. On the other hand, some demos are time-limited or have a separate save that cannot be carried over.

When It Doesn’t Carry Over

There are several scenarios where your demo progress won’t transfer:

Different game versions: If the demo is an older version or a special event version, it may not be compatible with the retail release.
Demo-specific content: Some demos include exclusive levels or modes that don’t exist in the full game, so progress in those areas is irrelevant.
Technical limitations: If the demo and full game use different save file formats (e.g., one uses a cloud save and the other doesn’t), transfer may be impossible.
Publisher choice: Some developers simply don’t implement save transfer. For instance, the Pokémon Sword and Shield demo (which was a special battle demo) did not carry over any progress to the main game because it was a separate experience.

If you’re unsure, the safest approach is to search online for “[game name] demo save transfer” or check the eShop description. Nintendo’s official support site also lists known transfer cases for first-party games.

How to Transfer Save Data (If Supported)

When a demo supports save transfer, the process is usually automatic. Here’s what you typically do:

Purchase and download the full game from the eShop.
Launch the full game. It will often detect the demo’s save data and prompt you to continue.
If no prompt appears, look for a “Transfer Save Data” option in the game’s main menu or settings.
In some cases, you may need to delete the demo after transferring, but that’s not always required.

For example, in Dragon Quest XI S, the full game automatically reads the demo’s save when you start a new game. In Octopath Traveler, the demo save is recognized when you select “Continue” in the full game. If you run into issues, try restarting the full game or checking for a system update.

Demo vs. Full Game: Save Data Differences

Even when transfer works, there are differences in how save data is handled. For instance, a demo might limit your save slots to one, while the full game offers multiple. Also, if the demo allows you to play beyond a certain point (some demos have no time limit but restrict the story), you might have to replay a section after transferring. For example, the Octopath Traveler demo only lets you play for a limited time (10 hours) and caps the level at 15, but your progress carries over. However, the full game has a different save structure, so you might need to start a new file and then import the demo data. Always read the instructions carefully.

Common Misconceptions

One common misconception is that all demos are time-limited. While some are (e.g., Octopath Traveler had a 10-hour limit), many demos are unlimited but restrict content (e.g., Dragon Quest XI S lets you play the first 10 hours without a timer). Another is that buying the full game will automatically overwrite the demo. That’s not true; the demo and full game are separate apps, and you can have both installed simultaneously. Finally, some players think that demo progress is stored on the cartridge (if you buy a physical copy), but save data is always on the console’s internal memory or an SD card, not on the cartridge.

How to Check Before You Buy

To avoid losing progress, do this before purchasing:

Read the demo’s eShop page. Look for a line like “Save data can be transferred to the full game.”
Check the game’s official website or social media for a FAQ.
Search for “[game name] demo save transfer” on a search engine or gaming forum.
If you’re still unsure, contact Nintendo Support or the game’s publisher.

For first-party Nintendo games (like Mario, Zelda, Splatoon), Nintendo usually ensures save transfer if a demo is released. For third-party games, it varies.

Frequently Asked Questions

Do I need to keep the demo installed after buying the full game?

No, you can delete the demo once your save data has been transferred. The full game will have its own save file. However, if you delete the demo before transferring, you may lose the ability to transfer (unless you re-download it). So, wait until the full game recognizes your progress, then delete the demo if you wish.

Will my demo progress carry over to a physical copy of the game?

Yes, usually. Save data is stored on the console, not on the cartridge. So, if you buy a physical copy, the full game will read the same save data as the digital version, as long as the game version is the same. Just insert the cartridge and launch the game; it should detect the save.

What if the demo and full game are from different regions?

This can be problematic. If you downloaded the demo from one region’s eShop and the full game from another, the save data may not be compatible because the game versions might differ. It’s best to use the same region for both. If you have a demo from a different region, you may need to delete it and download the correct one.

Can I transfer my demo save if I already started a new game in the full version?

Usually not. The transfer process typically happens when you first launch the full game. If you start a new game and then try to import the demo save, the game may not allow it. Some games offer a “Load Demo Data” option in the menu, but it’s not universal. If you’ve already started, you might need to delete your current save and start over to import the demo data.

Does the demo save count toward my total playtime?

No, the demo’s playtime is recorded separately. Your Nintendo Switch profile tracks playtime per software title, so the demo and full game are counted separately. This means your total hours in the full game won’t include the time spent in the demo.

Why does my demo save not show up in the full game?

First, ensure both are from the same region and are the same game version. Check if the game supports transfer (look for a note in the eShop). If it does, try restarting the full game. If it still doesn’t work, you may need to delete the demo and re-download it, or contact support. Some games require you to be connected to the internet for the transfer to work.
