Veritas NetBackup™ Appliance Upgrade Guide
About upgrading to NetBackup appliance software version 3.1.2
Starting with NetBackup appliance software version 2.7.1, Red Hat Enterprise Linux (RHEL) replaces the SUSE Linux Enterprise Server (SLES) operating system. You can upgrade any existing 5230, 5240, 5330, or 5340 appliances that currently use earlier software versions to version 3.1.2. In some situations, you may need to upgrade twice to get to version 3.1.2.
Starting with version 3.1, you can upgrade appliances by using the Appliance Management Console. Appliances that use software versions 2.7.3 and 3.0 are also supported for upgrades through the console, if the appropriate EEB is installed before the upgrade. For more information, see the Veritas Appliance Management Guide.
