The GG_SERVICE, GG_PASSWORD, DESTINATION, CREDENTIAL, DBPARAM, DBPARAMFILE, DBTEMPLATE, DBTEMPLATEFILE, NETPARAM and NETPARAMFILE parameters are only modifiable when the shard has not yet been deployed, since these parameters only have meaning for the deployment process and are no longer referenced once deployment has completed successfully.
