Chapter 1. New features


This section describes the new features of the Migration Toolkit for Applications (MTA) 5.3.0.

Analyze Known Libraries

You can now use the analyzeKnownLibraries advanced option to analyze libraries embedded within your applications. This feature lets you go beyond the default behavior of MTA, which is to only analyze application code.

Rules for migrating from OpenJDK 8 to OpenJDK 11

MTA now includes rules to help you migrate applications from OpenJDK 8 (Java 8) to 11.

Technology Reports

The technology reports have been enriched. The reports include new technologies, technology tags, and technology classifications.

Apply all Quick Fixes

In the MTA IDE plugins and extensions, you can now apply all suggested quick fixes at once, rather than one by one.

Rules for migrating from Spring Boot to Quarkus

Additional rules have been added to support migrating from Spring Boot to Quarkus.

Rules for migrating from IBM WebSphere to Open Liberty

A comprehensive collection of rules has been added to support migrating traditional IBM WebSphere applications to Open Liberty.

New OpenRewrite capabilities including additional recipes

  • The integration of MTA with OpenRewrite has been extended to support multiple migration paths.
  • An additional recipe for the javax to jakarta transformation path has been added, as well as the first Spring Boot to Quarkus recipe.
Important

OpenRewrite is provided as Technology Preview only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend to use them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

See Technology Preview features support scope on the Red Hat Customer Portal for information about the support scope for Technology Preview features.
