-snip- Pre-fork bitcoins (always in a non-custodial wallet) require splitting to avoid replay attacks.
Quite off-topic answer: As long as you're sending to your own wallet and it's non-custodial, you don't have to worry that much about 'replay attack'.
But that attack can still damage you if the "replayed" transaction's output isn't supported by the other fork, making it non-spendable or anyone-can-spend depending on the script;
so try to use the address type that's supported by most of those forks.

Or course the faster you can send the 'forked coins' to a new address after the first transaction (from any chain), the lower the risk.
Send/Sweep them to their respective wallets as fast as you can.
