- JBoss EAP schema uses different versions. Hence, JBoss EAP domain controller of a higher version must not have issues controlling a JBoss EAP host of a lower version, but the
domain.xmlmust be the
oldestof all the versions in use.
- If there is a cluster, all member servers of the cluster must belong to the same version of JBoss EAP.
- On every host in the domain, there are several Java processes like Process Controller, Host Controller and managed servers. These Java processes must be launched from the same installation of JBoss EAP, hence have the same version.
