Set schedule for upgrade:

To schedule an upgrade to a new client version at a specific block height, cosmovisor should already be running. Once confirmed, open a separate terminal and run:

source $HOME/.bash_profile
cosmovisor add-upgrade v0_6_5_2 $HOME/.kopid/cosmovisor/upgrades/v0_6_5_2/bin/kopid --force --upgrade-height 1350000
