Chapter 1. Introduction


1.1. About the MTA extension for Microsoft Visual Studio Code

You can migrate and modernize applications by using the Migration Toolkit for Applications (MTA) extension for Microsoft Visual Studio Code.

The MTA extension analyzes your projects using customizable rulesets, marks issues in the source code, provides guidance to fix the issues, and offers automatic code replacement, if possible.

The MTA extension is also compatible with Visual Studio Codespaces, the Microsoft cloud-hosted development environment.

1.2. About the Migration Toolkit for Applications

What is the Migration Toolkit for Applications?

The Migration Toolkit for Applications (MTA) is an extensible and customizable rule-based tool that simplifies the migration and modernization of Java applications.

MTA examines application artifacts, including project source directories and application archives, and then produces an HTML report highlighting areas needing changes. MTA supports many migration paths including the following examples:

  • Upgrading to the latest release of Red Hat JBoss Enterprise Application Platform
  • Migrating from Oracle WebLogic or IBM WebSphere Application Server to Red Hat JBoss Enterprise Application Platform
  • Containerizing applications and making them cloud-ready
  • Migrating from Java Spring Boot to Quarkus
  • Updating from Oracle JDK to OpenJDK

For more information about use cases and migration paths, see the MTA for developers web page.

How does the Migration Toolkit for Applications simplify migration?

The Migration Toolkit for Applications looks for common resources and known trouble spots when migrating applications. It provides a high-level view of the technologies used by the application.

MTA generates a detailed report evaluating a migration or modernization path. This report can help you to estimate the effort required for large-scale projects and to reduce the work involved.
