Naw, you're gonna have to install Atmosphere on your Switch to be able to backup and restore saves, man. Atmosphere supports 9.0.0, but only if you have a hackable Switch. So check your serial number and get yourself a jig if you've got a hackable Switch.
Final Edit: My bad. It helps when you follow directions. I didn't copy over the Hyne save in it's entirety into the Switch save, which is why it kept failing.
I fixed my stupid!
