Hacking Updating ACNL to the Welcome Amiibo version on a old method jailbroke 3ds?

[coztfu]

Hey.
I'm trying to update Animal Crossing NL to the Welcome Amiibo update to play online but I don't if it's safe to do it via the official way (Nintendo popup when opening).

The Nintendo is running on the Ver. 11.16.0-49U or 11.6.0-39U, don't recall which one exactly.
It also has the Luma3DS 6.6 version.

I heard that this Luma version indicates the hack used to jailbreak it was the arm9loaderhax.
Is there any way I can clarify this? I know there's a guide on 3DS Hacks guide to patch it from A9LH to boot9strap and that would problably solve the ACNL problem, but I'd like to confirm that the Nintendo is indeed using arm9loaderhax before doing anything else.

Also, I don't really want to lose my saves from the game. Will this be a problem?

Thankuu
