my custom controller configs were all saved to my Steam profile and auto-added on my oled once I signed in. same thing with my games that had online backup for the saves. I only had to manually move my non-steam game (along with its artwork) and I’ve made a backup of a game I had saved only to my deck (my kid played it on my desktop and it only has so many save slots, so I let those be the cloud backup)

my emudeck setup is a bit of a mess so I’m just keeping that backed up on ext hd and letting my oled have a clean setup. I’ll re-add those games as I want to play them.
