Upgrade to Appliance Controller 1.4.1.x

Feature Upgrade Packages

Prior to the Appliance Controller 1.4.1 release, all upgrade packages are specific to StorNext NAS and are referred to accordingly within this documentation center. Beginning with the Appliance Controller 1.4.1 release, upgrade packages encompass all Appliance Controller features and are referred to as Appliance Controller upgrades within this documentation center.

You can upgrade individual systems directly from StorNext NAS 1.2.5 to Appliance Controller 1.4.1.x. However, to upgrade NAS clusters to Appliance Controller 1.4.1.x, we recommend upgrading to StorNext NAS 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.


  • We strongly recommend upgrading to Appliance Controller 1.4.1.x before upgrading to StorNext 6.0.x.
  • You must be running Appliance Controller or later and StorNext Platform or later to use the iSCSI Network Connections feature on CentOS7-based appliances. See StorNext Appliances iSCSI.

  • Certain security fixes were included in the StorNext NAS release, but not the Appliance Controller 1.4.1 release. Users who upgraded directly from StorNext NAS or earlier to Appliance Controller 1.4.1 will not have these critical fixes. Therefore, for such users, we strongly recommend upgrading to Appliance Controller or later to access these critical security fixes. See Change Requests: Notes and Fixed Issues.


Additional Upgrade Information

  • Keep in mind that you will perform all configuration tasks from the Appliance Controller Console. To log in to the controller console, see Access the Appliance Controller Console.
  • Each node generally takes less than 5 minutes to complete the upgrade, and in many cases, each node will complete the upgrade between 30 seconds and 1 minute. Because the upgrade process could briefly interrupt access, we recommend performing an upgrade when minimal disruption to file access will occur.
