Hello. At some point in the past, we factored out the couch view names for actions and activations but not subjects. The subjects view name is hard coded in the code and not versioned. This makes it difficult to change that view. The view name should be factored into the db config object. I created an issue https://github.com/apache/openwhisk/pull/4610 andprepared a patch for the corresponding change for review and comments https://github.com/apache/openwhisk/pull/4611.
