14.1. About Patches and Upgrades
The patching mechanism 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 one-off, security, or cumulative updates.
Upgrading between major and minor releases of JBoss EAP (for example, from 6.1 to 6.2) requires a different process.
