1.2. About the Migration Guide

JBoss EAP 6 is a fast, lightweight, powerful implementation of the Java Enterprise Edition 6 specification. The architecture is built on the Modular Service Container and enables services on-demand when your application requires them. Due to this new architecture, applications that run on JBoss EAP 5 may need modifications to run on JBoss EAP 6.

The purpose of this guide is to document the changes that are required to successfully run and deploy JBoss EAP 5.1 applications on JBoss EAP 6. It provides information on how to resolve deployment and runtime problems and to how prevent changes in application behavior. This is the first step in moving to the new platform. Once the application is successfully deployed and running, plans can be made to upgrade individual components to use the new functions and features of JBoss EAP 6.
