Can you transfer your Diablo 4 character to Switch 2? Yes, although there is no traditional save-file transfer. Diablo IV progression is tied to Battle.net, so linking the Nintendo version to the same account is what makes the existing server-backed roster available.

The Short Answer
Yes, but it is not a traditional transfer. Diablo IV’s character roster is attached to Battle.net, so using the same linked account is what makes existing characters available on another supported platform.
Check Battle.net First
Log in to Battle.net and confirm which identity owns the characters before linking Nintendo. This is safer than discovering after setup that an old Xbox or PlayStation connection belongs to another account.
What Carries Over
Server-backed character progression and the online roster are the reason cross-progression works. You are accessing the same account data from new hardware rather than creating a cloned Nintendo save.
Nintendo Licence
Cross-progression is not cross-buy. A PC, Xbox or PlayStation licence does not grant the Switch 2 game, so you still need a valid Nintendo copy to launch it there.
Expansion Access
Content licences matter when a character has progressed into expansion areas. Blizzard says Age of Hatred includes the base game, Vessel of Hatred and Lord of Hatred, simplifying that transition.
No USB Transfer
There is no need to export a save to USB, copy a file through a PC or rely on Nintendo local-transfer tools for the Diablo character. Account authentication replaces that workflow.
Crossplay Uses the Same Identity
The same Battle.net model supports social continuity as well as progression. Changing hardware does not inherently mean leaving the Diablo friends list, seasonal roster or clan identity behind.
Account Unlinking
Platform links can be subject to restrictions and cooldowns. Do not disconnect long-standing Battle.net connections casually; the goal is to connect Nintendo to the correct existing identity.
A Safe Linking Checklist
Check the Battle.net email, open the connected-accounts page and make sure the platform where you currently play is already attached to that account. Only then add the Nintendo connection. There is no benefit to disconnecting an existing PlayStation or Xbox link just to make room for Switch 2, and unnecessary unlinking can trigger restrictions or cooldowns that are much harder to fix than taking two minutes to verify the account first.
If Your Characters Do Not Appear
Do not create replacement characters or start disconnecting accounts at random. First compare the Battle.net account shown on Switch 2 with the one used on the original platform. An empty roster usually points to the wrong account being linked rather than the server deleting progression. Because the characters are stored online, correcting the account identity is the important troubleshooting step; there is no local save file to recover.
No Character Conversion Needed
There is no special Nintendo version of a Barbarian, Sorcerer or seasonal character. Once the correct account is linked, the same roster is being accessed from another platform. That is why the process feels more like signing into an account than converting a save.
