I'm just a ghost.
The only way to save your catalog and all your DIYS that you learned is to transfer your Resident from your main switch to a 2nd switch that has a 2nd copy of the game. The problem is that you are the Resident Representative and it would not work like that. What you need to do is to create a new Resident on that same island and then transfer all of your items to that Resident, which can take a long while to do.I too have been thinking about reseting my island, but I'm unsure. My main problem is that I wish I had placed the town plaza in a different spot.
Does anyone know if you can keep your catalog after reseting or sell your island to Tom Nook like you could in NL ?
Once that done you have to get your 2nd switch that has a 2nd copy of the game and on the Main Switch press "minus" which will go into the settings menu where you see Tom Nook. What you want to do is select "Move to a new island" and when you do that he explains how the whole process works (trust me its a bit complicated to understand). Then when you do that go on the 2nd switch with the 2nd copy and make sure you're at the counter where Timmy and Tommy greet you. You would want to select "I'm moving"
Make sure on both switches send a request to find what Resident you picked that is moving. When it finds it, you would want to accept it and when it goes well they will accept you and you can turn off your main switch that you transferred your character from. Then finally when you get into your game, you will find that all of your catalog, bells, nook miles, and even your home are still there and Tom Nook even mentions that you payed your bill so you don't have to worry about paying him again.
