> UPDATED: 9/5/2024

| Binaries | Version | Mainnet |

{% endhint %}

{% hint style="danger" %}
Please note after updating it will take up to 6 hours maybe more to sync block replay.
{% endhint %}

## Step 1 - GHC and Cabal Check&#x20;

Make sure you are using ghc 8.10.7 and cabal 3.8.1.0. If already installed you can skip this step.

```
ghcup upgrade
ghcup install ghc 8.10.7
ghcup set ghc 8.10.7
ghcup install cabal 3.8.1.0
ghcup set cabal 3.8.1.0

ghc --version
cabal --version
```

## Step 2 - Backup your Configuration file:&#x20;

```
cd $NODE_HOME
cp mainnet-config.json mainnet-config.bak
mv mainnet-conway-genesis.json mainnet-conway-genesis.bak
```

## Step 3 - Download the new mainnet conway genesis file:

```
cd $NODE_HOME
wget https://book.play.dev.cardano.org/environments/mainnet/conway-genesis.json
mv conway-genesis.json mainnet-conway-genesis.json
```

## Step 4 - Update Config file:

```
cd $NODE_HOME
nano mainnet-config.json
```

Edit or add THESE TWO LINES to the following:

```
"ConwayGenesisFile": "mainnet-conway-genesis.json",
"ConwayGenesisHash": "15a199f895e461ec0ffc6dd4e4028af28a492ab4e806d39cb674c88f7643ef62",
```

## Step 5 - Download latest cardano-node git and checkout latest branch&#x20;

```
cd $HOME/git

git clone https://github.com/IntersectMBO/cardano-node.git cardano-node2

cd cardano-node2/

cabal update

git fetch --all --recurse-submodules --tags

git checkout tags/9.1.1
```

## Step 6 - Build the node

If you have tmux, it is recommended to open tmux by typing `tmux` this will allow to run these commands to build the node without terminal timing out.

```
cd $HOME/git/cardano-node2

cabal configure -O0 -w ghc-8.10.7

cabal build cardano-node
```

## Step 7 - Check cardano-node that the build was successful

```
$(find $HOME/git/cardano-node2/dist-newstyle/build -type f -name "cardano-node") version
```

✅if 9.1.1 - move to next step

## Step 8 - Download latest cardano-cli git and checkout latest branch

```
cd $HOME/git/cardano-node2/

git clone https://github.com/IntersectMBO/cardano-cli.git cardano-cli

cd cardano-cli/

cabal update

git fetch --all --recurse-submodules --tags

git checkout tags/cardano-cli-9.2.1.0
```

## Step 9 - Build the CLI

```
cd $HOME/git/cardano-node2/cardano-cli

cabal configure -O0 -w ghc-8.10.7

cabal build cardano-cli
```

## Step 10 - Check cardano-cli build was successful

```
$(find $HOME/git/cardano-node2/cardano-cli -type f -name "cardano-cli") version
```

✅if 9.2.1.0 - and you were using tmux, close tmux by typing `exit`

## Step 11 - Shut down the node and move the binaries to your bin

If on 9.1.1 node and 9.2.1.0 cli, then shut down the node and move the binaries to your bin

```
sudo systemctl stop cardano-node
```

```
sudo cp $(find $HOME/git/cardano-node2/cardano-cli/dist-newstyle/build -type f -name "cardano-cli") /usr/local/bin/cardano-cli

sudo cp $(find $HOME/git/cardano-node2/dist-newstyle/build -type f -name "cardano-node") /usr/local/bin/cardano-node
```

## Step 12 - Check that successful version upgrades then start back up Cardano node&#x20;

```
cardano-node version
cardano-cli version
```

✅If on 9.1.1 node and 9.2.1.0 cli move to next step

## Step 13 - Update and restart your instance

```
sudo apt-get update && sudo apt-get upgrade -y && sudo reboot
```

{% hint style="success" %}
Block replay will now start after reboot. This could take up to 6 hours. To check progress run:\
`journalctl -fu cardano-node`\
\
Use Ctrl+C command to exit the real time view.
{% endhint %}

## Step 14 - Clean up&#x20;

```
cd $HOME/git/

rm -rf cardano-node-old

mv cardano-node cardano-node-old

mv cardano-node2 cardano-node
```

## Additional Steps

Copy the cardano-cli binaries to your air gap machine. You can copy from your /usr/local/bin or from the new build to a USB drive

Check to see if you need to update other programs like CNCLI\
