Legacy Modernization with Claude Code: A Workflow for Product-Led Development
Claude Code make it easier for organizations to modernize any legacy product, without losing the business logic and product knowledge embedded in the old system. Using an internal HR application as an example, we show a product-led workflow that starts by extracting and validating functional requirements from the legacy codebase, then uses AWOS to turn those requirements into a structured roadmap, architecture, tasks, agent-driven implementation, and verification. Successful legacy modernization depends less on migrating old code or choosing the perfect stack and more on clearly defining the product, preserving what already works, and using a repeatable AI-assisted delivery workflow to rebuild faster and with less risk.
