Hardware O3ds xl CFW transfer to n3ds xl....safe?

[Shin Akuma]

Hi again guys
These days im expecting from post a n3ds xl.
I already have a 3ds xl with CFW(everything done from 3ds.guide) and i was wondering if its safe to do a system transfer from the3ds xl to the n3ds xl. Should i install CFW on the N3ds xl first?
Is the O3dsxl gonna get formatted afterwards?

Thanks for any response as always
