LLM-Assisted Java Modernization and Migration
Turn legacy Java into maintainable, standards-based, zero-dependency code. Learn how to extract specs and tests from existing applications, then migrate incrementally to modern JDKs, BCE, and MicroProfile, with LLMs and agents doing the mechanical work, and tests as verification loops.
🎯 Agenda
- LLM-assisted creation of OpenRewrite rules: generating recipes for repeatable, large-scale migrations
- Capturing the structure of existing databases with custom MCPs: exposing schemas to LLMs for context-aware migration
- Traceability: mapping legacy components to their migrated counterparts for auditable, verifiable migrations
- Spec-driven BCE (say "Space") migrations with SBCE
- Defining custom skills to capture transformation rules: reusable, shareable migration knowledge for developers and agents
- Reverse-engineering intent from undocumented legacy code
- Automating migrations with purpose-built agents
- TBD
