Please read this scenario prior to answering the question You are working as an Enterprise Architect consultant within a large manufacturing company. The company has multiple divisions located worldwide, including retail, manufacturing, pharmaceuticals, and technology. The company has a mature Enterprise Architecture (EA) practice and uses the TOGAF standard for its architecture development method. The EA practice is engaged throughout all the divisions, with governance provided by multiple Architecture Boards with responsibility for a business line. In addition to the EA program, the company uses several management frameworks, including business planning, project/portfolio management, and operations management. The EA program is sponsored by the Chief Information Officer (CIO). After a recent study, senior management is concerned about the impact of the company’s multiple data centers and duplication of applications on business efficiency. To address this concern, a strategic architecture has been defined; it will help improve the ability to meet customer demand and enhance operational efficiency. The strategic architecture involves the consolidation of multiple applications programs currently used in different divisions and putting them all onto a cloud-based solution instead. Each division has completed the Architecture Definition documentation to meet its own specific operational requirements. The enterprise architects have analyzed the corporate changes and implementation constraints. A consolidated gap analysis has been completed. Based on its results, the architects have reviewed the requirements, dependencies and interoperability requirements needed to integrate the cloud-based solution. The architects have completed the Business Transformation Readiness Assessment. Based on all these factors they have produced a risk assessment. They have also completed the draft Implementation and Migration Plan, the draft Architecture Roadmap, and the Capability Assessment deliverables. Due to the risks of changing from the current environment, the decision has been taken that a gradual approach is needed to implement the target architectures. It will likely take a few years to complete the entire implementation process. Refer to the scenario You have been asked to decide on the next steps for the migration planning. Based on the TOGAF standard, which of the following is the best answer?
