Popular Software Migration Strategies

• Lift-and-shift strategy involves transferring applications from their existing environment to a new one without significant changes in the code or architecture. This strategy has a quick and straightforward process, which minimizes disruption of the application’s functionality.
• Re-platforming entails migrating apps to a new platform or infrastructure with the help of modern technologies. This approach provides optimization and scalability while minimizing the need for extensive code alterations.
• Re-architecture involves redesigning apps to align them with new architectural patterns. This strategy focuses on improving scalability, flexibility, and performance by adopting microservices, containerization, or cloud-native approaches.
• Phased migration divides the process into several manageable stages or components. By migrating in increments, you can reduce risks by thorough testing and bug fixing, and migrate without disrupting the entire system at once.

• Hybrid model combines both on-premises and cloud-based environments, which enables a gradual transition of specific components while keeping others in the existing infrastructure. This approach provides flexibility, scalability, and a balance between legacy systems and cloud capabilities.
• Big bang strategy involves migrating all apps simultaneously from the legacy system to the new one. This synchronized process allows for a swift transition, which ensures that all components are migrated at once, thus minimizing the coexistence of two systems.
• Parallel approach involves running both the legacy and new systems simultaneously. This strategy allows for comprehensive testing, validation, and comparison between the two systems, ensuring that the new system is fully functional and reliable before completely transitioning from the legacy system.
• Service-oriented architecture (SOA) focuses on designing apps as a collection of loosely coupled and interoperable services. This approach promotes modularity, reusability, and easier integration during the process, which enables smoother transitions, more flexibility and adaptability.
