Chapter 2. Prepare for Migration

2.1. Prepare for Migration

Because the application server is structured differently than in previous versions, it is recommended that you do some research and planning before you attempt to migrate your application.

  1. Review What's New and Different in JBoss EAP 6

    A number of things have changed in this release that may impact deployment of JBoss EAP 5 applications. These include changes to the file directory structure, scripts, deployment configuration, class loading and JNDI lookups. See Section 2.2, “Review What's New and Different in JBoss EAP 6” for details.

  2. Review the Get Started documentation

    Be sure to review the chapter entitled Get Started Developing Applications in the Development Guide for JBoss EAP 6 on https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/?version=6.4. It contains important information about the following:
    • Java EE 6
    • The new modular class loading system
    • File structure changes
    • How to download and install JBoss EAP 6
    • How to download and install JBoss Developer Studio
    • How to configure Maven for your development environment
    • How to download and run the quickstart example applications that ship with the product.

  3. Learn How to Use JBoss EAP 6 Dependencies in your Maven Project

    Be sure to review the chapter entitled Maven Guide in the Development Guide for JBoss EAP 6 on https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/?version=6.4. The Manage Project Dependencies section contains important information on how to configure your project to use JBoss EAP Bill of Material (BOM) artifacts.

  4. Analyze and Understand your Application

    Each application is unique and you must thoroughly understand the components and architecture of the existing application before you attempt the migration.
