Chapter 1. Introduction
1.1. About the MTR extension for Microsoft Visual Studio Code
You can migrate and modernize applications by using the Migration Toolkit for Runtimes (MTR) extension for Microsoft Visual Studio Code.
The MTR 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 MTR extension is also compatible with Visual Studio Codespaces, the Microsoft cloud-hosted development environment.
1.2. About the Migration Toolkit for Runtimes
What is the Migration Toolkit for Runtimes?
Migration Toolkit for Runtimes (MTR) accelerates large-scale application modernization efforts across hybrid cloud environments on Red Hat OpenShift. This solution provides insight throughout the adoption process, at both the portfolio and application levels: inventory, assess, analyze, and manage applications for faster migration to OpenShift via the user interface.
MTR uses an extensive questionaire as the the basis for assessing your applications, enabling you to estimate the difficulty, time, and other resources needed to prepare an application for containerization. You can use the results of an assessment as the basis for discussions between stakeholders to determine which applications are good candidates for containerization, which require significant work first, and which are not suitable for containerization.
MTR analyzes applications by applying one or more rulesets to each application considered to determine which specific lines of that application must be modified before it can be modernized.
MTR examines application artifacts, including project source directories and application archives, and then produces an HTML report highlighting areas needing changes. MTR supports many migration paths including the following:
- 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
- Upgrading from OpenJDK 8 to OpenJDK 11
- Upgrading from OpenJDK 11 to OpenJDK 17
- Migrating EAP Java applicatons to Azure App Service
- Migrating Spring Boot Java applications to Azure App Service
For more information about use cases and migration paths, see the MTR for developers web page.
How does the Migration Toolkit for Runtimes simplify migration?
The Migration Toolkit for Runtimes looks for common resources and known trouble spots when migrating applications. It provides a high-level view of the technologies used by the application.
MTR 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.
