I know that if I restore an older nand I'd have to boot into OFW via the RCM bootloader, I was hoping that wouldn't be an issue since I wasn't planning on staying on 6.2.0 and was just going to use it as a starting point for a clean 7.0.x nand backup, but that's making me a little nervous, would Nintendo be able to see that I now have 9 fuses burned while I'm attempting to update?
Edit: I'm... feeling really stupid right now, so as it turns out I DO actually have a 7.0.1 nand backup, I didn't know it was because the backup folder had its directory name obfuscated for whatever reason, but after dumping my BIS keys and running FVI I can confirm that its an 7.0.1 (exFat) nand dump. I'm gonna take better care to not be that careless in the future, thanks for all the answers folks.
