Build a repeatable PHP-to-Java migration engine with Kiro

By · Published by Everything Blog

In short

The modernization framework relies on an eight-phase workflow, a mechanical discovery scanner, and a verification parity harness packaged into portable skill files. Developers can run these migrations step-by-step with approval gates inside the Kiro IDE or scale them autonomously across multiple codebases via AWS Transform. Refinements made during hands-on sessions automatically improve automated pipeline runs because both platforms share the exact same rulebooks. Implementing the engine requires an active Kiro workspace alongside PHP 8.0 or newer and Java 21 with Maven.

Build a repeatable PHP-to-Java migration engine with Kiro

When your team moves a mature PHP application to Java, you gain stronger type safety, broader library support, and more predictable scaling. A PHP codebase built over the years with Laravel, Symfony, or Doctrine carries business rules in places that are not obvious, from Eloquent traits to XML mapping files, so a structurally similar Java port can compile cleanly and still behave differently.

This post shows how to turn PHP-to-Java migration from a one-time leap of faith into a measurable, repeatable process using Kiro. Kiro is an AI integrated development environment (IDE) that pairs an AI agent with your codebase to run multi-step engineering tasks with you in the loop. The approach centers on a reusable engine: a shared methodology, a mechanical discovery scanner, and an eight-phase workflow. This engine treats the original PHP application as the specification and refuses to declare the Java port correct until a parity harness verifies it.

Prerequisites

Before getting started, you need:

- Familiarity with PHP (Laravel/Eloquent or Symfony/Doctrine). Java knowledge (Spring Boot, JPA)…
