Ah, I see. Unfortunately my own Switch doesn't meet the cutoff. Looks like I'll have to actually get a second Switch like the one you specified above since chip soldering is out of my element, and I don't believe I have the guts to try manually downgrading its firmware (not that I can anyways, since I only own a mac currently).
That being said, sorry I didn't manage to clarify what I actually wanted to do to bring my old mons into the current gen. I found a Gamefaq post that's somewhat similar to what I'm doing. I don't have any real way of transferring them up to SV so I was wondering if I could manually recreate them in HeX (albeit not perfectly, the only stuff I want to keep are the origin game, OT name, nickname, ball caught in, and whether or not they're shiny) and then port them over SV before sending them to Home. I understand this isn't possible due to the Home Tracker ID issue, so is there any workaround to this?
