Modernize Legacy Systems Without Breaking the Business
Tavant’s behavior-driven modernization approach uses AI to extract intent, lock system behavior before rewrites, and validate cutover with parallel run; reducing regression risk while accelerating modernization.
Problem
Legacy modernization fails when teams:
- Modernize what they think the system does; not what it actually does
- Rely on scarce SMEs to explain business rules and edge cases
- Cut over without confidence, leading to regressions, outages, and rework
