System Transfer with HyaCFW

So, I have a DSi XL with a legit copy of Four Swords and a couple other DSiWare games.
I have HyaCFW installed using the guide.

If I do a system transfer to a ofw N3DS will it brick my DSi?

(Thinking about I’d imagine it may kill the emunand on my SD card, but if I do a back up of that first, then restore after I think it’ll be ok?)
