I've just received my Steamdeck Oled. How to I transfer my profile from my original Steamdeck to my new Steamdeck Oled?
Although I don't have 2 Steam Decks, I transferred the profile from another computer to Steam Deck by enabling SSHD on the Deck and sending files to it with use of SCP protocol. It should be possible to connect with the other Deck in a similar way, i.e. first if you haven't done this yet, create a password for your deck account (it will be needed to use sudo), enable SSHD on one of the Decks and then use for example FISH protocol in Dolphin on the other Deck to connect to it over LAN (with "fish://deck@local_ip_address_of_the_deck_to_connect_to" and either send there the files, or grab the files from there. And no TSW doesn't use Steam cloud.
