Amazon's guide shows how to turn PHP-to-Java migration into a measurable, repeatable process using Kiro, an AI integrated development environment that pairs an agent with a codebase. The approach centers on a reusable engine: a shared methodology, a mechanical discovery scanner, and an eight-phase workflow that treats the original PHP application as the specification. The engine refuses to declare the Java port correct until a parity harness verifies it, and the post starts from an open repository so readers can run the engine themselves. Everything is packaged as skill files, versioned Markdown capability packages encoding the migration methodology and the discovery scanner workflow, so the same methodology runs in two ways. Kiro drives a migration step by step with explicit approval gates, letting developers review the discovery manifest, approve the rulebook, and sign off on each phase. AWS Transform, the AWS agentic AI service for large-scale migration and modernization, now integrates natively with Kiro and can run the same skill files agentically at portfolio scale. The scanner works in a single pass with no dependencies, applying three discovery strategies to source tokens and emitting one JSON manifest, with anything ambiguous routed to a review-flag queue for a human to resolve.

## Evidence

Verbatim from https://aws.amazon.com/blogs/machine-learning/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.
