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 lava
git clone https://github.com/lavanet/lava.git
cd lava
git checkout v4.0.0

# Build binaries
export LAVA_BINARY=lavad
make build

# Prepare binaries for Cosmovisor
mkdir -p $HOME/.lava/cosmovisor/upgrades/v4.0.0/bin
mv build/lavad $HOME/.lava/cosmovisor/upgrades/v4.0.0/bin/
rm -rf build

Thats it! Now when upgrade block height is reached, Cosmovisor will handle it automatically!
