Steps for upgrading Bor node

  1. Stop bor service

    sudo service bor stop

  2. Install Bor with a version tag, network name (amoy), and node type (sentry, validator, or archive).

    # Replace the node type
curl -L https://raw.githubusercontent.com/0xpolygon/install/main/bor.sh | bash -s -- v2.6.0-beta <network> <node_type>

  3. Check bor version

    /usr/bin/bor version

# It should print 
# v2.6.0-beta

  4. Restart bor service

    sudo service bor start
