Homebrew Recover Pokemon Sun save with save file

[XenoSlyr]

I have a backup of my old nand with all the games and saves in a folder on my pc. I restored my old nand, a put the Pokemon Sun .sav file from my old title folder. But when i try to open the app, it always says save data corrupt. I thougt that if you the same nand for your old saves, the title keys should link up. Im not entirely sure of this, not too knowledgeable on this. I would greatly appreciate if someone could help, I really dont feel like restarting this game.
