Question about Elgato Stream Deck

that is possible. The first hit on Google for the search "Copy Streamdeck settings" provides a link to a help page from Elgato where this is explained in detail.

If the settings contain paths, e.g. to self-defined icons, these must of course be found in the same place on both computers.
