Upgrade to NAS 1.4.0.x

You can upgrade individual StorNext NAS systems directly from version 1.2.5 to 1.4.0.x. However, to upgrade NAS clusters to 1.4.0.x, we strongly recommend upgrading to 1.3.0 first. StorNext NAS 1.3.0 provides the automatic NAS cluster upgrade feature, allowing you to upgrade an entire NAS cluster with one command. See NAS Upgrades.
