Chapter 10. Upgrading Red Hat JBoss Data Grid for OpenShift Between Releases

Rolling upgrades of JBoss Data Grid allow you to upgrade a cluster from one version to a new version without experiencing any downtime.

For complete details on rolling upgrades with JBoss Data Grid, see Rolling Upgrades in the JBoss Data Grid documentation.

Important

As of 7.2, JBoss Data Grid supports rolling upgrades using Hot Rod only. In earlier releases, JBoss Data Grid allowed you to perform rolling upgrades using the REST interface.

Additionally, JBoss Data Grid supports rolling upgrades using Hot Rod from version 6.6.2 and later. If you plan to perform a rolling upgrade from a version earlier than 6.6.2, you must first upgrade to JBoss Data Grid 6.6.2.
