Upgrading colonies in sharded mode

After moving colonies from the production environment to the upgrade environment, run a complete upgrade in sharded mode, where <INSTALL_DIR> corresponds to Upgrade_V2, and <INSTALL_DIR_OLD> corresponds to Upgrade V1. When you perform a sharded upgrade, all colonies in the upgrade environment are upgraded, which includes the colonies' shards, such as the STATISTICS and TRANSACTION/MASTER shards.
