Chapter 1. Introduction

1.1. About the CLI Guide

This guide is for engineers, consultants, and others who want to use the Migration Toolkit for Applications (MTA) to migrate Java applications or other components. It describes how to install and run the CLI, review the generated reports, and take advantage of additional features.

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:

  • Migrating from enterprise application servers to Red Hat JBoss Enterprise Application Platform
  • Containerizing applications and making them cloud-ready
  • Migrating from Spring Boot to Quarkus
  • Updating OpenJDK versions

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.

How do I learn more?

1.3. About the CLI

The CLI is a command-line tool in the Migration Toolkit for Applications that allows users to assess and prioritize migration and modernization efforts for applications. It provides numerous reports that highlight the analysis without the overhead of the other tools. The CLI includes a wide array of customization options, and allows you to finely tune MTA analysis options or integrate with external automation tools.

For more information on using the CLI, see the MTA CLI Guide.
