# This script will initiate the transition to protocol version 2 (Shelley).

# In order for this to be successful, you need to already be in protocol version
# 1 (which happens one or two epoch boundaries after invoking update-1.sh).
# Also, you need to restart the nodes after running this script in order for the
# update to be endorsed by the nodes.
