[QUESTION] Possible to export Users from emunand and import it to new emunand?

[rusagent]

Using NXNandMananger and HackDiskMount for this.

Hey - i was reading that the file that contains the users is on the SYSTEM partition in the saves folder and is called 8000000000000010.
My old emunand was on fw version 10.0.4 - the new emunand is 10.0.2. I copied over the file to the new emunand SYSTEM saves folder but now i'm stuck at the Splash Screen which shows "NINTENDO SWITCH". Could it be because of the different firmware versions or did i do something fundamentally wrong?

Would love to get help on this because i had loooooads of saves on my user that i don't want to lose. ( I already transfered the savefiles in the same fashion like i did with the userfile but in the USER partition.

Actually i updated the Emunand to 10.0.4 but came to the same never ending NINTENDO SWITCH splash.

edit: I actually need to use PC tools to do this because my old SD card doesn'T work on my switch anymore. ( i had to send it in because the sd card reader was broken - nintendo replaced the whole motherboard to an erista patched one which couldn't be jailbroken without a modchip. Got an sx core and flashed it with spacecraft-nx. When i try to import my old emunand backup Got an sx core and flashed it with spacecraft-nx. When i try to import my old emunand backup (system and user or even fullnand) as soon as i get to the splash from atmosphere the switch goes black and doesn't continue.. So there is no easy way for me to import my old stuff. :(
