CDH upgrade effect on existing non-default configuration values

For each of our customer clusters we export / maintain a cluster non-default configuration file.  In the event the cluster configuration drifts, we reapply the non-default configs using the Cloudera Manager API. 


How do CDH upgrades treat existing non-defaults?   If there is a new default value for a given service config parameter, would the upgrade override any existing non-default value defined for that parameter?
