Upgrade to 1.35.2 from 1.3x.x

if you are upgrading from older versions (1.29.0 or older) this upgrade will resync/replay all the blocks, so be ready that after the upgrade the node, depending on your server specs, will take some (30min - 2h) time to start.
Quick update guide for SPOs who have the previous version already installed  1.30.x
If you are  installing from scratch, then follow the installation guide: https://cardano-node-installation.stakepool247.eu/​
1. backing up current binaries
cd ~/.local/bin/
​
# let's create a folder with the version number
mkdir -p $(cardano-node version | grep -oP '(?<=cardano-node )[0-9\.]+')
​
# copying files to the created folder
cp cardano-node $(cardano-node version | grep -oP '(?<=cardano-node )[0-9\.]+')/
cp cardano-cli $(cardano-node version | grep -oP '(?<=cardano-node )[0-9\.]+')/
2. Upgrading and updating the system packages
# let's update the system first
sudo bash -c 'sudo apt-get update -y; sudo apt-get upgrade -y'
3. Updating the Cardano node requirements
ghcup install ghc 8.10.7
ghcup install cabal 3.6.2.0
ghcup set ghc 8.10.7
ghcup set cabal 3.6.2.0
sudo apt install -y libsodium-dev libtool autoconf make
mkdir -p ~/git && cd ~/git
rm -rf secp256k1
git clone https://github.com/bitcoin-core/secp256k1
cd secp256k1
git checkout ac83be33
./autogen.sh
./configure --enable-module-schnorrsig --enable-experimental
make
sudo make install
4. Proceeding with Cardano Node binary updates
# let's create a directory where we will be downloading source code
cd ~ && mkdir -p git
cd git
# just in case you already had a source directory with cardano-node source code - let's delete it and download fresh one.
rm -rf cardano-node
# let's clone source code from git
git clone https://github.com/input-output-hk/cardano-node.git
​
cd cardano-node
git fetch --all --recurse-submodules --tags
​
# checking out the 1.35.2 version
git checkout tags/1.35.2
​
# adding extra flags for libsodium library
echo "package cardano-crypto-praos" >>  cabal.project.local
echo "  flags: -external-libsodium-vrf" >>  cabal.project.local
echo "with-compiler: ghc-8.10.7" >> cabal.project.local
# now let's compile the code
cabal build all
And now we wait...  it could take some while (1h+ ) to compile, depending on your server's CPU 
Before the next step -  STOP your node so it doesn't lock the carano-node file for overwriting
sudo systemctl stop cardano-node
mkdir -p ~/.local/bin
cp -p "$(./scripts/bin-path.sh cardano-node)" ~/.local/bin/
cp -p "$(./scripts/bin-path.sh cardano-cli)" ~/.local/bin/
​
# let's check if we have successfully installed the latst cardano-node and cardano-cli versions.
which cardano-node && which cardano-cli
cardano-node --version
cardano-cli --version
you should now have similar output:
5. Updating systemd service file
we need to add Environment variable LD_LIBRARY_PATH for node to work correctly.
Mainnet
TestNet
sudo rm /etc/systemd/system/cardano-node.service
cat <<EOF | sudo tee -a /etc/systemd/system/cardano-node.service
[Unit]
Description=Cardano Pool
After=multi-user.target
[Service]

​

[Install]

EOF
sudo systemctl daemon-reload
sudo rm /etc/systemd/system/cardano-node.service

​
​
Restart=on-failure
RestartSec=45s
WorkingDirectory=~
User=cardano
Group=cardano
[Install]
WantedBy=multi-user.target
EOF
sudo systemctl daemon-reload
Now we can start the cardano node process
sudo systemctl start cardano-node
and check the log files if everything is starting up as planned:
journalctl -u cardano-node.service -f -o cat
that's it - you have upgraded your node to the latest cardano-node version, now do the same update on all of your other production servers (or copy generated cardano-cli / cardano-node bin files).
