Have you inherited a legacy codebase and are unsure where to begin? This course teaches you how to use GitHub Copilot and other AI coding assistants to understand unfamiliar code, identify bugs, security risks, and technical debt, generate protective tests, refactor safely, review pull requests, and plan a controlled modernization.
AI-Assisted Legacy Code Review and Modernization teaches a repeatable, review-first workflow for understanding, testing, improving, and modernizing inherited software. You will use AI as an investigation and implementation assistant while keeping evidence, validation, and engineering judgment at the center of every decision.
This course isn’t about asking AI to rewrite a legacy application and hoping the result works. The focus is disciplined software engineering: establish a baseline, use AI to accelerate investigation, verify findings against the source code, generate protective tests, review every change, and document the evidence needed before modernization work is accepted.
