I am trying to create a situation in which I have two ArcGIS Portal accounts, one will be for production and another for development/staging. When moving stuff from staging to production, I actually want to just switch my portal DNS to the staging environment, and then use the former production environment for staging and development. Is there a proper way to do this? Is it possible to create this type of setup with the licensing as is for ArcGIS? What would I need to do to ensure smooth transition from one server to another?
