sorry for maybe asking dumb questions but I prefer better being safe than sorry when it comes to preventing noob bricks.

so I just did a system transfer from my freshly completed Old Launch 3DS to my New MM 3DS XL 11.0.0-33E while following this guide keep in mind I never installed anything on this New 3DS XL before following this guide to downgrade it with DSiware. and I'm at section VII step 2 but I saw this when reading further down.

Do NOT downgrade with dgTool on a device that already has arm9loaderhax installed or you will BRICK!
so when checking my SD card and saw some a9lh files and I started questioning myself

Spoiler

so do these files (NANDmin.bin, arm9loaderhax.bin, start_Hourglass9.bin) that got transferred from my o3DS impact my downgrade or not when following this guide ?

If they got transferred when you did the system transfer then no, they shouldn't impact anything.
I'm not 100% sure about this, but I don't know how these files could impact anything,
since they're just NAND-Backups and payloads you can use once you've installed A9LH.
A9LH itself doesn't get transfered afaik, otherwise we could just system transfer a 3DS that was already hacked to a new one and that would be it.
Correct me if i'm wrong though, guys.

You should probably clean up (delete) those files on the SD card but the console itself won't have a9lh.

I recently successfully installed a9lh and luma3DS on all of my 3DS's, but now my last question is what are the the do's and don'ts

in terms of
- should I dump every Nand possible ?
- should I update if its get prommed ?
- should I play my backed up games online ?
- ect.............

and also thanks for the replies when I was tuck
