How AI Agents Modernize Code **[IBM Technology](https://daily.dev/sources/ibmtechnology)** · 10 min read · 0 upvotes · 0 comments ## Summary Agentic coding uses AI agents to autonomously analyze codebases, map hidden dependencies, and guide safe modernization of legacy systems. Using a financial services Java application as a case study, the post walks through a five-step iterative modernization cycle: analyzing the codebase to surface undocumented behavior, identifying safe boundaries for change, generating test coverage including edge cases, having developers review and approve proposals, and running old and new services in parallel to catch divergences early. Key safeguards — human approval gates, full Git history, and no autonomous deployment — keep the process trustworthy for regulated environments. The result is developer time shifting from legacy code archaeology to actual feature delivery. ## Full article daily.dev links to this article rather than hosting it.
