Explanation
Developer and Technical Architect are two team members that should be included during a Maps scoping session in which legacy data/mapping system migrations and integrations/interfaces will be discussed. These team members have the technical expertise and skills to assess the feasibility, complexity, and risks of migrating and integrating data from different sources and systems. They can also provide guidance and recommendations on how to design, develop, test, and deploy the data migration and integration solutions.
These team members are part of the Salesforce Maps Implementation Methodology document.
