ArchiMate Migration Viewpoint
The Migration Viewpoint specifies the transition from an existing architecture to a desired architecture using the concepts of plateau and gap elements.
A Plateau provides an overview of the state of an architecture.
A Gap shows the delta information from one Plateau (representing the overview of one state of an architecture) to another Plateau (representing the overview of a ‘to be’ state of an architecture).
The ArchiMate elements that can be drawn on this diagram are:
Plateau
Gap
