Key details at a glance

The strangler-fig pattern incrementally replaces legacy modules (auth, orders, reporting) one slice at a time, rather than attempting a risky full rewrite. Four modernization strategies exist: Rehost (lift-and-shift, fastest/lowest payoff), Replatform (same code, new runtime), Refactor (strangler-fig, usually the right answer), and Replace (buy SaaS when legacy isn't a differentiator). Most real modernization programmes blend two or three of these strategies rather than picking just one. India 2026 cost ranges: audit + roadmap (₹6–18L), strangler-fig mid-size migration (₹35L–1.2Cr), full platform re-platforming (₹1.2–3Cr).
