Dont get how that will work out.

Coins on exchange will be swapped by exchange?
Bitcoin Fast -v3.1.1.0-release - dumpprivkey <bitcoinfastaddress> , then importprivkey <bitcoinfastaddress> to new Bitcoin-fast core wallet.
"then, send coins from the old wallet to a specific address, and the system will send new coins to the same address that the coins were received from."

sorry for the delay - been busy

the new wallet uses the same first letter a the old wallet. (base58 prefix)
so you can export the keys from the old wallet, and import them to the new wallet - and have the same address on the new chain.

my swapping app will be looking for incoming transactions on the old chain, and will send the new coins from the new wallet to the same address on the new chain.
