Hacking How to remove Gateway A9LH properly

[Wargla]

I installed last summer Gateway A9LH on my Old 3ds.
Everything is up to date:
- Sysnand 4.4.0 and I have a NAND.bin of my console
- Emunand 11.2.0

Now I would like to remove Gateway A9LH properly and install A9LH for Luma + Luma.
I would like to avoid doing any mistake.

I am planning to do the following:
1. To put on root of my SD card my NAND.bin
2. To stop Gateway boot in order to enter in Gateway menu.
3. To press Up key and select DOWNGRADE, in order to flash again my sysnand 4.4.0 with NAND.bin
4. And then to follow plailect guide in order to install A9LH for Luma + Luma.

Could you please confirm this is what need to be done to avoid any brick ? DO I need to format entirely my SD card between step 3 and step 4 to remove entirely EMUNAND created with Gateway ?

Thanks.

If you follow the guide on 11.2 emunand, you should (afaik) end up with an 11.2 luma a9lh sysnand, it flashes emunand onto sysnand.
