Redelegating genesis keys

In a real-life scenario, a holder of a genesis key may wish to delegate to a new key.

Generate a new (Shelley era) delegation key pair:

cardano-cli genesis key-gen-delegate \
--verification-key-file delegate-keys/new.shelley.delegate.000.vkey \
--signing-key-file delegate-keys/new.shelley.delegate.000.skey \
--operational-certificate-issue-counter-file delegate-keys/new.shelley.delegate.000.certificate.counter

Issue a new delegation certificate for genesis key 000:

cardano-cli governance create-genesis-key-delegation-certificate \
--genesis-verification-key-file genesis-keys/non.e.shelley.000.vkey \
--genesis-delegate-verification-key-file delegate-keys/new.shelley.delegate.000.vkey \
--vrf-verification-key-file bft0/shelley.000.vrf.vkey \
--out-file genesis-keys/genesis.delegation.cert

Submit the certificate in a transaction. It must be signed with the genesis key:

cardano-cli query utxo --address $(cat utxo-keys/user1.payment.addr) --testnet-magic 42
                           TxHash                                 TxIx        Amount
