Idea Summary
Might be good to have a “keep current” authentication schema after replacing an application. Similar to the settings.  Another way to solve this is to support a dynamic value for “Discovery URL”. That might be from an application setting or from a local table. In that case, the same authentication could be used across environments.

Use Case
if you have more than 1 authentication schema (IDCS test and IDCS prod for instance), is annoying that the current schema will be overwritten in PROD by the one current in DEV. 

Preferred Solution (Optional)
Either to have a flag to keep the current authentication schema or to have a dynamic Discover URL in the Social Sign In plugin
