# From Shelley to Alonzo

## The Allegra hard fork

Continue upgrading your system to later eras. First, move from Shelley to Allegra. To achieve this, upgrade to protocol version 3.0:

{% tabs %}
{% tab title="Linux" %}

```bash
sed -i configuration/config.json \
-e 's/LastKnownBlockVersion-Major":2/LastKnownBlockVersion-Major":3/' \
-e 's/"MaxKnownMajorProtocolVersion":2/"MaxKnownMajorProtocolVersion":7/'
```

{% endtab %}

{% tab title="macOS" %}

```bash
gsed -i configuration/config.json \
-e 's/LastKnownBlockVersion-Major":2/LastKnownBlockVersion-Major":3/' \
-e 's/"MaxKnownMajorProtocolVersion":2/"MaxKnownMajorProtocolVersion":7/'
```

{% endtab %}
{% endtabs %}

Create the proposal:

```bash
cardano-cli governance create-update-proposal \
--genesis-verification-key-file genesis-keys/non.e.shelley.000.vkey \
--genesis-verification-key-file genesis-keys/non.e.shelley.001.vkey \
--out-file transactions/update.v3.proposal \
--epoch $(cardano-cli query tip --testnet-magic 42 | jq .epoch) \
--protocol-major-version "3" \
--protocol-minor-version "0" 
```

{% code overflow="wrap" %}

```bash
CHANGE=$(($(cardano-cli query utxo --address $(cat pool1/payment.addr) --testnet-magic 42 --out-file  /dev/stdout | jq -cs '.[0] | to_entries | .[] | .value.value') - 1000000))
```

{% endcode %}

```bash
cardano-cli transaction build-raw \
--shelley-era \
--fee 1000000 \
--invalid-hereafter $(expr $(cardano-cli query tip --testnet-magic 42 | jq .slot) + 1000) \
--tx-in $(cardano-cli query utxo --address $(cat pool1/payment.addr) --testnet-magic 42 --out-file  /dev/stdout | jq -r 'keys[]') \
--tx-out $(cat pool1/payment.addr)+$CHANGE \
--update-proposal-file transactions/update.v3.proposal \
--out-file transactions/update.v3.proposal.txbody
```

```bash
cardano-cli transaction sign \
--tx-body-file transactions/update.v3.proposal.txbody \
--signing-key-file pool1/payment.skey \
--signing-key-file bft0/shelley.000.skey \
--signing-key-file bft1/shelley.001.skey \
--out-file transactions/update.v3.proposal.txsigned
```

```bash
cardano-cli transaction submit --testnet-magic 42 \
--tx-file transactions/update.v3.proposal.txsigned
```

Wait for the next epoch transition to see the Allegra hard fork.

## The Mary hard fork

To get to the Mary era, upgrade to protocol version 4.0:

{% tabs %}
{% tab title="Linux" %}

```bash
sed -i configuration/config.json \
-e 's/LastKnownBlockVersion-Major":3/LastKnownBlockVersion-Major":4/'
```

{% endtab %}

{% tab title="macOS" %}

```bash
gsed -i configuration/config.json \
-e 's/LastKnownBlockVersion-Major":3/LastKnownBlockVersion-Major":4/'
```

{% endtab %}
{% endtabs %}

```bash
cardano-cli governance create-update-proposal \
--genesis-verification-key-file genesis-keys/non.e.shelley.000.vkey \
--genesis-verification-key-file genesis-keys/non.e.shelley.001.vkey \
--out-file transactions/update.v4.proposal \
--epoch $(cardano-cli query tip --testnet-magic 42 | jq .epoch) \
--protocol-major-version "4" \
--protocol-minor-version "0" 
```

{% code overflow="wrap" %}

```bash
CHANGE=$(($(cardano-cli query utxo --address $(cat pool1/payment.addr) --testnet-magic 42 --out-file  /dev/stdout | jq -cs '.[0] | to_entries | .[] | .value.value') - 1000000))
```

{% endcode %}

```bash
cardano-cli transaction build-raw \
--shelley-era \
--fee 1000000 \
--invalid-hereafter $(expr $(cardano-cli query tip --testnet-magic 42 | jq .slot) + 1000) \
--tx-in $(cardano-cli query utxo --address $(cat pool1/payment.addr) --testnet-magic 42 --out-file  /dev/stdout | jq -r 'keys[]') \
--tx-out $(cat pool1/payment.addr)+$CHANGE \
--update-proposal-file transactions/update.v4.proposal \
--out-file transactions/update.v4.proposal.txbody
```

```bash
cardano-cli transaction sign \
--tx-body-file transactions/update.v4.proposal.txbody \
--signing-key-file pool1/payment.skey \
--signing-key-file bft0/shelley.000.skey \
--signing-key-file bft1/shelley.001.skey \
--out-file transactions/update.v4.proposal.txsigned
```

```bash
cardano-cli transaction submit --testnet-magic 42 \
--tx-file transactions/update.v4.proposal.txsigned
```

Wait for the next epoch transition to see the Mary hard fork.

## The Alonzo hard fork and the Alonzo intra-era hard fork

Getting to Alonzo will require the Alonzo hard fork AND the Alonzo intra-era hard fork, which means that you need to move from protocol version 4.0 to 5.0 and then to 6.0:
