Since we are using Cosmovisor, it makes it very easy to prepare for upcomming upgrade. You just have to build new binaries and move it into cosmovisor upgrades directory.
Download and build upgrade binaries
# Clone project repository
cd $HOME
rm -rf celestia
git clone https://github.com/celestiaorg/celestia-app.git celestia
cd celestia
git checkout 2.3.1
# Build binaries
make build && make install
# Prepare binaries for Cosmovisor
mkdir -p $DAEMON_HOME/cosmovisor/upgrades/2.3.1/bin && cp $HOME/go/bin/celestia-appd $DAEMON_HOME/cosmovisor/upgrades/2.3.1/bin
$DAEMON_HOME/cosmovisor/upgrades/2.3.1/bin/celestia-appd version
rm -rf build
Thats it! Now when upgrade block height is reached, Cosmovisor will handle it automatically!
