An explanation for idiot on dumping my purchased E-shop titles like how I did with disc-2-app

I would like to backup up my legit digital downloads in the same format as disc-2-app does, so that if my Wii U frys I can just install them on another wii U.
I've tried to follow tutorials, and explanations, but I'm just confused. I've done this with my old Wii Shop games. I think there are pieces missing in the explanations because of anti pirate policies, but I'm trying to do this legit. The Eshop is not going to be around forever, and I want to be playing these games on the original system like how I still play Wrecking Crew on my NES.

So, I need to dump the games, dump my traffic tickets or something, write a ticket to the public somehow, and then use my traffic ticket to pay the public ticket? Or something like that.
Then compile it all into disc-2-app wup format?
I've got dumpling, and a usb helper of some sort. I also read something about loadvine or iine, or whatever.

Can someone do a "Dumping your digital games & DLC for dummies?" for me.

Like
Step 1: Get your private traffic tickets with this app.
Step 2: Use this tool to dump the game| DLC
Step 3: Pay your tickets and convert to WUP.
Step 4: Store in freezer until apocalypse, and restoration is needed.


Thanks.

 

The ones I can find all talk about dumping for CEMU, I want to dump to WUP so I can install them back on an unfried Wii U
