Just a quick question that someone here may know: I have a Steam Machine coming and I'm looking to swap the SSD in my Steam Deck (2 TB) with the SSD in the Steam Machine (512 GB). As far as I know, the SM comes with a 2230 SSD so it'll fit in the Steam Deck, but I'm curious if the install is different enough that I should backup and re-image the 2 TB drive before I put it in the Steam Machine or if I can just swap the two drives.

I'm assuming I have to re-image each drive with a SteamOS USB installer, but if I could just hotswap them it'd make life easier. Just not sure how much device-specific code is part of the install.

Thanks for the advice, everyone! I'm using rsync to back up my home directory on the Deck right now, and I've migrated a lot of my smaller games I'll want to have access to on both the Machine and Deck to a 256 GB microSD I had lying around (including my RetroDeck setup). I've also flashed the SteamOS installer onto a thumb drive.

I think I'll plan to just try putting the Deck SSD into the Steam Machine and see if it boots up and runs properly or not. If it looks like there's any issues, I'll just reinstall SteamOS on it and restore some of the files I'll want to from the backup external drive.

Then I'll do the same with the SM SSD in the SD, reinstall if anything's funky, and then copy files from the backup onto it again (though most of those will be mods and such for larger games that'll just live on the Steam Machine now, so it should be light work).

Just need to make sure to have a list of my Decky plugins in case I need to wipe things and make a list of the Flatpaks I've installed.
