Upgrading from 1.25.1 to 1.26.1

Upgrade from 1.25.1 to 1.26.1
If you are running version 1.25.1 you need to upgrade your pool. Please use the instructions below to upgrade your pool.​
you will have to create a backup of your binaries
cd .local/bin/​# let's create a folder with the version numbermkdir -p $(cardano-node version | grep -oP '(?<=cardano-node )[0-9\.]+')​# copying files to the created foldercp cardano-node $(cardano-node version | grep -oP '(?<=cardano-node )[0-9\.]+')/cp cardano-cli $(cardano-node version | grep -oP '(?<=cardano-node )[0-9\.]+')/
now we need to update and upgrade the packages
sudo apt-get update -y
sudo apt-get upgrade -y​
now we need to create a directory where we will download the code
cd ~
mkdir -p source
cd source
rm -rf cardano-node
lets download the source from git
git clone https://github.com/input-output-hk/cardano-node.git
​
cd cardano-node
git fetch --all --recurse-submodules --tags
​
git checkout tags/1.26.1
 update cabal and install using GHC
cabal clean
cabal update
​
cabal configure --with-compiler=ghc-8.10.2
Adding flags for the libsodium library
echo "package cardano-crypto-praos" >>  cabal.project.local
echo "  flags: -external-libsodium-vrf" >>  cabal.project.local
build all
​
NOW YOU HAVE TO STOP YOUR NODE before running commands below!
mkdir -p ~/.local/bin/
cp -p dist-newstyle/build/x86_64-linux/ghc-8.10.2/cardano-cli-1.26.1/x/cardano-cli/build/cardano-cli/cardano-cli ~/.local/bin/
cp -p dist-newstyle/build/x86_64-linux/ghc-8.10.2/cardano-node-1.26.1/x/cardano-node/build/cardano-node/cardano-node ~/.local/bin/
Check if you have installed everything correctly.
cardano-node --version
cardano-cli --version# let's check if we have successfully installed the latst cardano-node and cardano-cli versions.which cardano-node && which cardano-clicardano-node --versioncardano-cli --version
cardano-node --version cardano-node 1.26.1 - linux-x86_64 - ghc-8.10 
 cardano-cli --version cardano-cli 1.26.1 - linux-x86_64 - ghc-8.10 
now you can copy the archive to other machines, to producer and other relays if you have them
tar -czvf archive.tar.gz ~/cnode/db ~/.local/bin/cardano-node ~/.local/bin/cardano-cli
 Copy the file to the server that you want to upgrade (insert IP of another machine)
 scp archive.tar.gz [email protected]_remote_server_ip:/home/cardano/
if you want to connect to server with ssh (replace also the public key with your filename)
scp -i ~/.ssh/id_rsa archive.tar.gz [email protected]_ip:.
now you need to unzip the files on the server where you copied them to
tar -xvf archive.tar.gz 
Now stop the cardano node and run the following commands. You need to remove the old db, move the new db and replace binaries
cd
rm -rf ~/cnode/db 
mv home/cnode/db ~/cnode/db
mv home/.local/bin/* ~/.local/bin 
you are all done. you can start the node
