Legacy modernization is not just a technology project — it is a business transformation. At Codazz, we use strangler-fig patterns and blue-green deployments to migrate your systems incrementally, ensuring zero downtime and zero data loss. Every project includes rollback procedures, data validation, and comprehensive knowledge transfer. You see measurable improvements within weeks, not months.
