The core problem is that coding agents lack type-awareness, leading to compilation errors and deprecated method usage. The recommended approach combines deterministic tools like OpenRewrite (via Tanzu CLI or App Advisor MCP server) with AI agents: use deterministic recipes for predictable migration patterns (e.g., Spock to JUnit), and reserve AI agents for non-deterministic edge cases. For scale, this process should be automated via CI/CD pipelines rather than triggered manually by developers, reducing token costs and improving consistency across hundreds of repositories. ## Full article daily.dev links to this article rather than hosting it.
