I have a running baking server and want to upgrade my signer setup to use a Ledger Nano S.
Per default the Nano S creates it's own seed and addresses, but I want to keep the delegators and baking history of my current address.
How can I migrate my Tezos baking private keys to the Nano S?
I have tried initializing a fresh Nano S, installed the Ledger Tezos app on it and linked it to a fresh TezBox installation. I can't find any option to import a private key to the Nano S.
