Kiro enables repeatable PHP-to-Java migration engine with eight-phase workflow

Kiro, an AI-integrated development environment, transforms PHP-to-Java migration into a measurable and repeatable process using a shared methodology and an eight-phase workflow. The engine treats the original PHP application as the specification and refuses to declare the Java port correct until a parity harness verifies behavioral consistency. It operates in two modes: interactive Kiro with developer approval gates, and AWS Transform for large-scale, agentic migration at portfolio scale.
