Enterprises today maintain sprawling ecosystems—backend services, frontend apps, shared libraries, and configuration artifacts—across diverse languages. Manually upgrading APIs, patching frameworks, and enforcing security is slow, inconsistent, and error-prone. This leads to mounting technical debt and compliance gaps that expose organizations to risk.

Polyglot migrations become possible by leveraging OpenRewrite’s automation. By applying semantic, AST-driven "recipes" across multiple languages and tiers, teams can refactor Java, JavaScript, and Python codebases in one coordinated effort—updating APIs, remediating vulnerabilities, and modernizing frameworks. OpenRewrite, enhanced by Moderne, offers native support for these languages, build systems, and config formats, enabling safe, traceable transformations across the enterprise

Attendees will gain a clear migration playbook: how to integrate automated cross-language refactoring into CI/CD, how to measure impact via reduced cycle time and stronger security posture, and how to architect sustained code hygiene. Armed with these insights, decision-makers can justify investing in scalable, enterprise-grade modernization.
