Legacy Modernization: The 24-Month Roadmap
Navigating the complexities of decoupling legacy monoliths without disrupting $2B in annual revenue streams.

Legacy modernization is rarely a clean-room rebuild. The organizations that succeed are those that approach transformation as a series of calculated, incremental moves rather than a single Big Bang migration.
Phase 1: Discovery & Assessment
The first six months should be dedicated entirely to understanding what you have. Map every dependency, every integration point, every undocumented behavior. The cost of discovery is a fraction of the cost of a failed migration.
Phase 2: Strangler Fig Pattern
Rather than replacing the monolith wholesale, we progressively route traffic to new microservices while the legacy system continues to operate. This approach minimizes risk and allows for continuous validation.
"The best migration is one your customers never notice."
