Usage:
  peer chaincode upgrade [flags]

Flags:
  -C, --channelID string               The channel on which this command should be executed
      --collections-config string      The fully qualified path to the collection JSON file including the file name
      --connectionProfile string       Connection profile that provides the necessary connection information for the network. Note: currently only supported for providing peer connection information
  -c, --ctor string                    Constructor message for the chaincode in JSON format (default "{}")
  -E, --escc string                    The name of the endorsement system chaincode to be used for this chaincode
  -h, --help                           help for upgrade
  -l, --lang string                    Language the chaincode is written in (default "golang")
  -n, --name string                    Name of the chaincode
  -p, --path string                    Path to chaincode
      --peerAddresses stringArray      The addresses of the peers to connect to
  -P, --policy string                  The endorsement policy associated to this chaincode
      --tlsRootCertFiles stringArray   If TLS is enabled, the paths to the TLS root cert files of the peers to connect to. The order and number of certs specified should match the --peerAddresses flag
  -v, --version string                 Version of the chaincode specified in install/instantiate/upgrade commands
  -V, --vscc string                    The name of the verification system chaincode to be used for this chaincode

Global Flags:
      --cafile string                       Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint
      --certfile string                     Path to file containing PEM-encoded X509 public key to use for mutual TLS communication with the orderer endpoint
      --clientauth                          Use mutual TLS when communicating with the orderer endpoint
      --connTimeout duration                Timeout for client to connect (default 3s)
      --keyfile string                      Path to file containing PEM-encoded private key to use for mutual TLS communication with the orderer endpoint
  -o, --orderer string                      Ordering service endpoint
      --ordererTLSHostnameOverride string   The hostname override to use when validating the TLS connection to the orderer
      --tls                                 Use TLS when communicating with the orderer endpoint
      --tlsHandshakeTimeShift duration      The amount of time to shift backwards for certificate expiration checks during TLS handshakes with the orderer endpoint
      --transient string                    Transient map of arguments in JSON encoding
