Hacking Is it possible/How to get Luma/A9LH on N3DS with already cfw'd N3DS

[AhTa]

So I have two N3DS' sitting around the house, one has luma/a9lh and the other is on firmware 11.2. Is it possible to use the already cfw'd 3ds to get luma/a9lh on the other 3ds?

Any help would be appreciated even if its just a link to where I can find the answer.

Thank you!
