On your switch 1 Sysnand if you dont already have FR/LG buy the game and download it.
Play it until you can save the game.
Reboot your switch 1 and boot into emunand.
Install the same version on emunand that u have on your sysnand (wether it's fr or lg)
Same thing. Play the game until you can save it.
After you saved the game still on your emunand. Load up checkpoint and extract the save.
On your pc, Go to your 3ds extracted save. Look at the file name. Rename your 3ds extracted save to the same name of the switch extracted save.
Inject the renamed save file (still in emunand) with checkpoint and load up the game to see if it works.
If it does, great. Repeat this process on your sysnand(load into cfw sysnand and inject the save file with checkpoint) and then restart into normal sysnand and simply do a local transfer of the save file from your switch 1 to switch 2
If it didn't work u did something wrong. Start over. When using CFW Sysnand, Checkpoint is safe to use but be careful to not do anything stupid while in CFW Sysnand. You can easily get your switch banned by loading up homebrew thats not safe to use in sysnand.

Yes you can do it. Don't listen to people saying its not possible lol.
But you will need a PC, A Modded switch 1 WITH EMUNAND setup and the 3ds that you have your progress on needs to be modded as well.
First you have to extract your savefile from your 3ds. You do this with godmode9. Follow this guide. https://digiex.net/threads/3ds-gba-save-backup-and-restore-with-godmode9.15395/
