The next step, involves kick-starting the various projects emerging from your application rationalization initiative. Having established LeanIX as the single source of truth for applications and cloud migration, take it a step further by instigating the actual migration. As we strongly advocate for a federated approach to enterprise architecture, we believe that the responsibility for documenting these changes should ultimately rest with the respective stakeholders (domain/solution architects, project managers, etc.) in the long run. While an enterprise architect can help initiate the process and provide guidance, the collaboration of all stakeholders is crucial. Bring together all stakeholders to examine the relevant fact sheets and address key questions:
- Will the functional and technical fit improve?
- What will be the future hosting type?
- Will the lifecycle undergo changes?
- Which IT components will see modifications?
This collaborative approach ensures comprehensive consideration and effective decision-making throughout the migration process.
