Activity: Develop a Migration Plan
The purpose of this activity is to define a migration plan to take the enterprise from an existing IT environment to the defined target architecture.
Work Breakdown Structure
Purpose
When the Technical Perspective is completed then a migration plan can be defined. It specifies how to move from the current situation to the target IT architecture as defined by the Technical Perspective.
Description
To develop a migration plan a current environment is compared with a target architecture and the differences noted. Knowledge of dependencies between components, technologies, processes and systems, among other aspects, is then used to order these steps into a logical sequence of activities, with the end result being the enterprise's environment ending up in the target state as defined by the target enterprise architecture.
