Question

A client uses a model-driven app that is deployed by using a managed solution in the production environment. The app contains only entities and UI components and has no custom code or extensions to the platform. The client needs an exact copy of the app with a different name in the production environment. You need to recreate this app in production without disrupting the end users. What should you do?

Explanation

The requirement is to create an exact copy of a managed model-driven app with a different name in the same production environment without disturbing end users. Option B - creating a new model-driven app and selecting 'Use existing solution to create the App' - lets you reference the same underlying components (entities, views, forms) already present in the managed solution, giving the new app its own identity. Option A (Save As) is not available for apps deployed via managed solutions. Option C (Clone solution) copies the entire solution, not just the app, and can disrupt managed-solution integrity. Option D (manually recreating every component) is error-prone and time-consuming. Option E involves exporting and importing which is unnecessary complexity for a same-environment copy.
