Can I use any eMMC board to rebuild a NAND?

[WayOfTheRoad]

Hi, all.
Can I use any working Switch eMMC board on a Switch it did not ship with IF my plan is to rebuild the NAND with the keys of the new Switch?

Put simply, "Switch A" is broken but the eMMC board is still good. "Switch B" works fine in every way except it has a bad EMMC board. If "Switch B" is an unpatched unit and I have all of it's keys, can I use the eMMC from "Switch A" in it for NAND rebuild or does the eMMC have to be reset/erased in some way first?

Thanks!

I believe it is possible.

Ok, thank you so much for the reply! I wasn't sure if the ones I bought from China were wiped and/or by necessity. Given that I have working donors from unfixable Switch tablets, I could hopefully save myself the time and money.

Don't you need to dump keys from the donor switch? Not sure if you can do that with just its emmc board.
Btw i'm referring to this gude:
