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 agoric-upgrade-15-rc0
git clone agoric-upgrade-15-rc0
cd agoric-upgrade-15-rc0
git checkout agoric-upgrade-15-rc0

# Install and build Agoric Javascript packages
yarn install && yarn build

# Install and build Agoric Cosmos SDK support
(cd packages/cosmic-swingset && make)

# Prepare binaries for Cosmovisor
mkdir -p $HOME/.agoric/cosmovisor/upgrades/agorictest-upgrade-15/bin
ln -s $HOME/agoric-upgrade-15-rc0/bin/agd $HOME/.agoric/cosmovisor/upgrades/agorictest-upgrade-15/bin/agd

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