If you’re upgrading from an original Switch, the good news is straightforward: nearly all of your existing library — physical cartridges and digital purchases alike — works on Switch 2 without any extra steps.
The rule: broad, not universal
Backward compatibility covers the large majority of the original Switch catalogue, both physical and digital. That said, “nearly all” is doing real work in that sentence — this isn’t a blanket 100% guarantee, and the exceptions fall into specific, identifiable categories rather than being random or unpredictable.
The three categories of actual exceptions
Confirmed incompatibilities fall into three buckets: certain streaming apps that depended on service-specific backend support rather than the game itself, titles that depend on specific accessories that may not carry the same functionality forward, and a small number of games or peripherals that rely on hardware Switch 2 physically doesn’t replicate. This isn’t a large or growing list of ordinary games failing to work — it’s a narrow, specific set of edge cases.
Some games get more than just compatibility — they get upgraded
A handful of existing Switch titles have received, or are expected to receive, free patches specifically improving their graphics and performance when played on Switch 2 hardware. Super Mario Odyssey and Splatoon 3 are both examples of games getting this treatment — meaning for some of your library, upgrading hardware doesn’t just mean “it still works,” it means “it now runs and looks better,” at no additional cost.
What this means practically before you upgrade
If you’re deciding whether to upgrade to Switch 2, the backward-compatibility picture removes one of the biggest traditional console-upgrade anxieties — losing access to your existing library. The practical exception check worth doing before upgrading is specifically around any accessory-dependent games or streaming-service apps in your library, since those are the identified categories where compatibility isn’t guaranteed, rather than assuming your entire library is equally safe.
The practical takeaway
For the overwhelming majority of Switch owners, upgrading to Switch 2 means your existing library travels with you intact, and in some specific cases (Mario Odyssey, Splatoon 3) actually improves for free — the exceptions are narrow, specific, and worth a quick check only if your library includes streaming apps or accessory-dependent titles.
