I installed and configured my node by following the tutorial from Coincashew. Currently running with version 1.29.0, could someone give a procedure to upgrade my node to the higher version safely?

1.30.1 release note: All SPOs and node users must update to this (or a later) version prior to the HF to Alonzo PV 6, or risk not being able to sync to the network.

IMPORTANT: As usual, don’t forget to backup your nodes before starting these updates.

STEP 1 - Clone the latest source and checkout the branch 1.30.1

cd $HOME/git
git clone https://github.com/input-output-hk/cardano-node.git cardano-node2
cd cardano-node2/
git fetch --all --recurse-submodules --tags
git checkout tags/1.30.1

STEP 2 - Make sure to have at least ghc 8.10.4 and cabal

ghcup upgrade
ghcup install ghc 8.10.4
ghcup set ghc 8.10.4
ghc --version
ghcup install cabal
ghcup set cabal
cabal --version
cabal update

STEP 3 - Configure & Compile

cd $HOME/git/cardano-node2
cabal configure -O0 -w ghc-8.10.4
echo -e "package cardano-crypto-praos\n flags: -external-libsodium-vrf" > cabal.project.local
cabal build cardano-node cardano-cli

Now make sure that your version of your freshly built cardano-cli and cardano-node is correct (1.30.1):

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

STEP 4 - Shut your node down, replace your old binaries with the new ones in your bin folder and start your node again

Stop the node

sudo systemctl stop cardano-node

Replace old binaries with the new ones

sudo cp $(find $HOME/git/cardano-node2/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

Double check the version

cardano-node version
cardano-cli version

Start your node again

sudo systemctl start cardano-node

Check the logs:

journalctl --unit=cardano-node --follow 

Now clean your mess

cd $HOME/git/
mv cardano-node cardano-node-old
mv cardano-node2 cardano-node
