9.1. About Patches and Upgrades
Patching in JBoss EAP 6 applies updates which are made available to a specific minor version of JBoss EAP 6, for example JBoss EAP 6.2. Patches can contain individual or cumulative updates.
Upgrading is the process of moving to a newer major version (for example, from 5.0 to 6.0) or newer minor version (for example, from 6.1 to 6.2), and cannot be done via patching.
