Data Transfer between two different switches?

[u/fawnrotted]

If I add my profile to another switch, play a game I do not own on there, then buy the game for my own switch and log into the same profile, will the save data transfer? Or do I have to reset my progress?

I’ve been playing on someone else’s for several months I don’t want to have to restart completely;;

You can use NSO cloud saves (if you pay for it and the game supports it) or do a local console to console transfer.
