All you need are the 24 words. And if you're really paranoid, just commit them to memory.Moving it is pretty straightforward just like moving it anywhere else. I'd get two of whatever hardware wallet you use and make one a backup. Store it at a separate secure location. Like in case your house burns down. Only write your seed phrases down and never store it on your phone or computer. Keep your copies in separate secure locations separate from your wallets. Depending on the amount of crypto you have and your level of paranoia anyway you may not need all this though.
