Quick question, is it possible to transfer the armory_randomkey_.wallet files to different machine then restart armory on the other computer to have the wallet on the new machine?
Yes. You can just copy the files over, and even have multiple instances of Armory running at the same time with the same wallets. (Such behavior, of course, isn't recommended.) Just place the wallets wherever each version of Armory looks for wallets, and you're good to go.
