SwitchPresence-Rewritten VS JKSV

Installed JKSV saves manager on the hacked switch and backed up all of the saves on the switch. Make sure to save a copy of these game backups in case anything goes wrong. JKSV created folders for each of the games on the SD card.

Assuming you have both of them homebrewed (PC/Linux program to convert Wii U <-> Switch BOTW saves) https://github.com/DeltaJordan/BotW-Save-Manager (Switch homebrew app for exporting/importing/backup game saves) https://github.com/J-D-K/JKSV Use JKSV to import the save into the game once you got the save converted and onto the sd card in your switch. I don’t know how to get the save from the Wii U though, that you’ll have to research.

This reentry guide section has steps for migrating, since it migrates your SX OS EmuNAND over if you have one and your SysNAND is completely unaffected by the change in CFW, I'd presume that moving saves would be unneeded, however if you want to be on the safer side, you can always back up your saves using JKSV or another save backup tool of your choice.

I saw a post on this sub reddit where they posted a link yo the save manager. I just redownloaded it and replaced the file. Heres the link; JKSV save manager

I personally use JKSV, which is something you run on the Switch to dump your saves to the SD card so you can extract it using either DBI or just through the Hekate payload's USB tools

The way I do it is by installing this program. The 3ds homebrew website (found here) has a very easy-to-follow guide on how to install the program if you haven't got it already. Once you are inside of the program it's very easy to understand what to do - I think you just press A to make a new backup and Y to restore and existing one, or something like that.
