Right now I have a 2tb SSD inside my old LCD deck that I would like to put inside my LE Deck, but I’m curious if I’ll need to find the steamOS 3.5.5 image and do that whole process again. I was also planning on giving the LCD one to my brother once I’m done, would the 1tb SSD that’s inside the OLED deck need to be reformated as well?
Update the LCD deck to the highest software, then swap the drives. It’s what I did. And in less than 10 minutes I had my deck fully up and running with 1.5tb of games.
I’m now the proud owner of a 2tb LE steam deck! Thanks for your help! Ignore how long that took me, doing this is my second time doing any amount of technical technician fixing kind of thing with an electronic, the first time being putting in the 2tb and formatting it the first time. It worked exactly as you said! Just swapped em and put them back together
