Just send the funds to the other devices' wallets. 1 satoshi / byte won't hurt that much.
The most easy way would be to export all private keys and import them again to the new devic(es).
This only works if all the private keys are in the same format, example WIF.
That's the
more complicated way than restoring the seed phrase or reinstalling the app (import wallet.dat/wallet file).
Imagine if he got more than 30 addresses with funds in that wallet.
