Chapter 1. Introduction

1.1. About the CLI Guide

This guide is for engineers, consultants, and others who want to use Red Hat Application Migration Toolkit (RHAMT) 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.

1.1.1. Use of RHAMT_HOME in This Guide

This guide uses the RHAMT_HOME replaceable variable to denote the path to your RHAMT installation. The installation directory is the rhamt-cli-4.2.0.Final directory where you extracted the RHAMT ZIP distribution.

When you encounter RHAMT_HOME in this guide, be sure to replace it with the actual path to your RHAMT installation.

1.2. About Red Hat Application Migration Toolkit

What is Red Hat Application Migration Toolkit?

Red Hat Application Migration Toolkit (RHAMT) is an extensible and customizable rule-based tool that helps simplify migration of Java applications.

RHAMT examines application artifacts, including project source directories and application archives, then produces an HTML report that highlights areas needing changes. RHAMT can be used to migrate Java applications from previous versions of Red Hat JBoss Enterprise Application Platform or from other containers, such as Oracle® WebLogic Server or IBM® WebSphere® Application Server.

How Does Red Hat Application Migration Toolkit Simplify Migration?

Red Hat Application Migration Toolkit looks for common resources and highlights technologies and known trouble spots when migrating applications. The goal is to provide a high-level view into the technologies used by the application and provide a detailed report organizations can use to estimate, document, and migrate enterprise applications to Java EE and Red Hat JBoss Enterprise Application Platform.

1.3. About the CLI

The CLI is a command-line tool in the Red Hat Application Migration Toolkit 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 the RHAMT analysis options or integrate with external automation tools.
