How adaptable is your technology stack to changes in business requirements, technological advancements, and the availability of new and better tools? When you can more easily secure, upgrade, move, or modernize your code, that means you can adapt quickly and efficiently to changes in technology and markets. That’s what Migration Engineering is all about—and what we’ll be exploring in this workshop.

We’ll discuss and demonstrate how to create custom recipes using OpenRewrite, an open source auto-refactoring tool that enables large-scale code analysis and transformations. You’ll learn the make-up of recipes as we walk through a number of examples, then we’ll demonstrate how to write code search and transformation actions that are custom to your organization. We will assemble these recipes with the visitor pattern, and show how to stitch recipes together with YAML, with Refaster-style templates, with Semgrep matchers, etc. We’ll also show how Generative AI can be applied to accelerate recipe development.

This is a comprehensive look at all kinds of recipe development that will enable you to come away fully equipped to plan and exercise large-scale code transformations in your organization.
