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. This reduces regression risk while accelerating modernization in environments where teams often modernize what they think the system does rather than what it actually does. They rely on scarce SMEs to explain business rules and edge cases and cut over without confidence, leading to regressions, outages, and rework.
What is Provided in the Blueprint
Legacy Modernization Blueprint (3–4 weeks, fixed fee)
System intent + dependency discovery summary
Business capability map + modernization prioritization
Recommended modernization path per component
Behavior lock-in test strategy (to minimize regressions)
Data migration integrity approach (if relevant)
Pilot plan: scope, success metrics, timeline, and investment estimate
This is ideal for teams modernizing business-critical platforms where downtime, regressions, and compliance risk aren’t acceptable.
