OP
Here's the quick qnd dirty answer.
First figure out what type of EmuNAND you have. (Btw EmuNAND and EMMC are the same thing)
Do you have a folder named Emutendo in the root of your card? If so your EmuNAND was a SXOS EmuNAND originally. You should have an EMMC folder. There is an INI file inside. Can you copy the contents of the INI file here? Just use a text editor. Next to verify, because laziness is the bane of tech support, put the SD in your PC. In disk management, where is the EmuNAND located? It will appear as a RAW or UNFORMATTED section before or after the FAT32 partition. SX EmuNANDs are a hidden partition at the beginning of the SD, Atmosphère's EmuNAND is at the end of the SD. Once you figure out what EmuNAND type you have, back it up using EmuTool, make sure to choose the correct source type.
Backing up your old SD presents no data loss risk. Just do not delete or format the old card until the new one is up and tested.
It doesn't really matter what type the EmuNAND was originally, except when backing it up. Atmosphère can see both types when configured correctly. The INI file points to your EmuNAND and the data folder (emutendo or emmc).
On the new card, create a fresh new EmuNAND using hekate then use emutool to restore the backup from the old SD. It will overwrite the new blank EmuNAND and you'll have your EmuNAND on your new SD. Make sure you copy your data folder too (emutendo or emmc). Don't overwrite the ini that hekate made in the EMMC folder.
That's the jist. I'm on my phone and away from my desktop. Sorry for any typos and the lack of clearer more concise instructions. Let me know if you have questions.
I'd like to point out, if you want to add LINUX(L4T) or Android (Switch root) now is the time as they have special formatting requirements. But that's a whole other conversation. Tutorials are in the tutorial section.
Fyi,what I said earlier was true,all this information is out there. Check out the tutorial

I think it was linked earlier in this thread. The goal of the tutorial isn't to copy the EmuNAND but I explain these concepts and I think you could have a better grasp on what's going on here.
Maybe I'll write a new one for this purpose. An all around EmuNAND guide. Maybe.
