5.3.3. Upgrade JBoss EAP Cluster from 6.2 to 6.3
Prerequisites
- None
Summary
JBoss EAP 6.3 does not support the creation of clusters where the different nodes are made up of different versions of JBoss EAP servers. Thus, a mixed cluster based on different versions is not supported and all nodes within a cluster must be the same version - 6.3.
Warning
The upgrade process for migrating traffic from a 6.2 cluster to a 6.3 cluster is therefore based on transferring all traffic to the 6.3 cluster and then shutting down the servers or nodes in the 6.2 cluster.
Procedure 5.9. Setup a JBoss EAP Cluster in 6.3
- Refer to the HTTP Clustering and Load Balancing chapter of the JBoss EAP 6.3 Administration and Configuration Guide for instructions on how to setup a JBoss EAP cluster in 6.3.
- Migrate all traffic to this new cluster using the steps outlined in the Migrate Traffic between Clusters chapter of the JBoss EAP 6.3 Administration and Configuration Guide
Result
Your JBoss EAP 6.2 cluster has been migrated to a cluster based on JBoss EAP 6.3.
