Migrationsscenarier

Migrationsscenarier refers to the hypothetical situations or planned courses of action that describe how data, applications, or entire IT infrastructures will be moved from one environment to another. These scenarios are crucial for effective planning and execution of migration projects, whether it involves moving from an on-premises data center to a cloud platform, upgrading hardware, or consolidating systems. Each scenario outlines the specific steps, resources, timelines, and potential risks associated with a particular migration approach.

Common migration scenarios include lift-and-shift, re-platforming, re-architecting, and re-purchasing. A lift-and-shift scenario involves moving an application or data as-is to the new environment with minimal changes, often chosen for its speed and simplicity. Re-platforming involves making some modifications to the application to take advantage of the new environment's capabilities, such as migrating a database to a managed cloud service. Re-architecting entails significant changes to an application's architecture to fully leverage the benefits of the target platform, which can improve scalability and performance but requires more effort. Re-purchasing involves replacing an existing application with a new, cloud-native solution.

The selection of a migration scenario depends on various factors, including business objectives, technical requirements, budget constraints, and the complexity of the existing systems. Thorough analysis of these factors allows organizations to choose the most suitable scenario that balances cost, time, and risk while achieving the desired outcomes of the migration. Well-defined migration scenarios are essential for minimizing disruption, ensuring data integrity, and maximizing the return on investment for IT modernization efforts.
