Legacy Modernization FAQs
We employ the Strangler Fig pattern: deploying an API gateway in front of the monolith and carving out microservices incrementally while the legacy application remains fully operational.
We use Change Data Capture (CDC) via Kafka or AWS Kinesis to stream database changes asynchronously between old and new stores with sub-second synchronization.
We reverse-engineer business logic through traffic shadowing, log analysis, and automated contract testing before refactoring code paths.
Initial domain extraction typically ships within 8 to 12 weeks, followed by phased iterative migrations over 6 to 18 months depending on estate complexity.
