4. Leverage Middleware Solutions ? Utilize API gateways or ESB (Enterprise Service Bus) to bridge old and new systems. ? Implement message brokers (Kafka, RabbitMQ) for asynchronou communication. 5. Ensure Data Interoperability ? Use ETL (Extract, Transform, Load) processes to migrate and synchronize data. ? Maintain consistent data formats across old and new systems via schema validation. 6. Automate Testing & Monitoring ? Utilize CI/CD pipelines to ensure seamless updates and integrations. ? Monitor system health using observability tools like Prometheus, Grafana, or Splunk. By following these steps, you can minimize integration risks, reduce downtime, and ensure a seamless transition between legacy and modern architectures.

If the new architecture is not compatible, a way must be found for them to coexist through intermediate systems that allow it.

I start by reviewing our current setup to spot any potential conflicts. Then, I use APIs or middleware to connect old and new systems smoothly. Rolling out changes step by step and testing along the way helps avoid major disruptions.

I am currently working on adding middleware to enhance the system's functionality and ensure seamless communication between different services. This middleware acts as a crucial layer, handling data transformation, authentication, and error management. It's the solution to improving efficiency, scalability, and integration within the architecture.

All of this seems pretty on the nose. I would recommend developing test procedures, anticipating each phase of development as much as possible.
