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 stargaze
git clone https://github.com/public-awesome/stargaze stargaze
cd stargaze
git checkout 14.0.0
# Build binaries
make build && make install
# Prepare binaries for Cosmovisor
mkdir -p $DAEMON_HOME/cosmovisor/upgrades/14.0.0/bin && cp $HOME/go/bin/starsd $DAEMON_HOME/cosmovisor/upgrades/14.0.0/bin
$DAEMON_HOME/cosmovisor/upgrades/14.0.0/bin/starsd version
rm -rf build
Thats it! Now when upgrade block height is reached, Cosmovisor will handle it automatically!
