What the Title says:

I got lucky enough and was able to order a SteamDeck OLED today. I would like to clone my current Deck as it is to my new OLED.

I would rather not set up EMUDECK my non Steam Games and so on all over again. PLus I don’t want to lose Save Games of Games that do not support Cloud Save.

What would be the easiest way to do this?

I currently have the 512 LCD Version and will get the 1 TB OLED Version. I do have a 512 SD Card for File Transfer.
