Drupal Feature pushed to staging site
When you have an existing feature and you are changing some configurations which are stored in the feature, you have to update your features

drush fua 


does an update on all enabled features. After that you deploy your features (propably using git) an then you have to accept the changes done to your feature on the production side.

drush fra 


(feature revert all) does the trick.
