Rolling upgrade for library mode.

Latest response

When we try to validate the Data Grid functionality, few queries has been raised relate to upgrade.

  1. Will it be possible to upgrade Data-Grid from one version to another without having downtime in a library mode.
  2. Will it be possible to form a cluster with two different versions of Data-Grid.

These features will reduce cluster downtime during the upgrade.

Hi,

Yes, the new version of JDG as well as upcomming versions, have added support for rolling upgrades.

This new feature enables you to upgrade your cluster from JBoss Data Grid version 6.1 to the next version without any downtime.

Currently this is available only for deployments accessed remotely via Hot Rod protocol.

Hi,

We found that JDG 6.1 is latest and plan to use it.
Is this feature already available with 6.1?
