I just got a switch 2 and I migrated my switch 1's virtual Pokemon Scarlet game card from my original switch to the new switch 2. Both systems are signed into the same Nintendo Switch Online + Expansion Pack account. I did not choose any options to sync data between the two systems aside from loading two virtual game cards.
When I started up Scarlet on the Switch 2, it gave me the beginnings of an entire new game. I transferred the virtual game card back to the old system, and it loaded my existing game file.
Can I do both? I want to keep the save file I have, but I would love to start a new game at the same time with online access and keeping them on different systems is no issue for me.
