Back to the future - how we integrated a 40 year old software system by Lukas Pradel
Integrate legacy software systems with caution and clarity, avoiding replica APIs and leveraging the right tools and expertise to ensure a smooth and scalable migration.
- Don’t underestimate the complexity of integrating legacy software systems.
- Pay attention to the details, as even small issues can lead to significant problems.
- Focus on understanding the legacy system, including its functionality and architecture.
- Use a clear and straightforward approach to integration, avoiding replicas of the legacy system’s API.
- Choose the right tools for the job, considering factors like timeouts, caching, and service mesh.
- Recognize the limitations of the legacy system, including performance and scalability issues.
- Consider future-proofing the new system by planning for potential updates and changes.
- Don’t underestimate the importance of naming conventions and cache invalidation.
- Integrate the legacy system slowly and iteratively, testing each step carefully.
- Be prepared for unexpected issues and plan for contingencies.
- Don’t assume that technology will last forever; anticipate the need for updates and replacements.
- Make sure to document the integration process and keep the knowledge up-to-date.
- Encourage communication and collaboration between teams working on different aspects of the integration.
- Avoid treating legacy systems as black boxes, and instead seek to understand their internal workings.
- Use architecture decision records to document decisions and reasoning.
- Be patient and persistent when integrating legacy software systems, as it may take time to overcome challenges.
