Hardware Dead Switch help

[kraoro]

My Switch stopped booting/charging and I suspect it's one of the ICs that commonly fail. The repair cost is higher than just buying a new mainboard, though. So my question is, if I replace the mainboard, could I restore my NAND backup to the new board, or is that somehow tied to the internal emmc storage? And if it's the latter, could I just take the eemc chip off the old Switch and put it on the new board?

eMMC data encrypted to individual SOC, unless you have the prod.key and dump & decrypt then transfer to new NAND
