About client upgrades
Once the primary and the media servers for a client computer are upgraded, you can upgrade the client computer. Do not upgrade a client computer before the associated primary and media server are upgraded.
From a NetBackup perspective, client computer upgrades present minimal concerns. The client computers have minimal NetBackup binaries and no NetBackup databases. From the customer perspective, however, the client computers may host mission critical databases or unique business-specific applications. As such, review your client computers and determine where you need to engage additional resources to ensure uninterrupted access to important databases and applications.
NetBackup supports four client upgrade methods:
NetBackup upgrade script. The NetBackup upgrade script is the standard upgrade method and is recommended for new users. More information is available.
See Performing local, remote, or clustered server upgrades on Windows systems.
See Upgrading UNIX and Linux clients with the NetBackup upgrade script.
Native UNIX and Linux installers. The native UNIX and Linux installers are potentially more difficult and require additional steps. More information is available.
See Upgrade of the UNIX and Linux client binaries with native installers.
VxUpdate. VxUpdate is the replacement for LiveUpdate and lets you schedule the client upgrade for your client computers. More information is available.
See About VxUpdate.
Ansible playbooks. More information is available.
Note:
Before you begin an upgrade, disable antivirus software.
If the antivirus software cannot be disabled, you should exclude NetBackup files and folders from virus scan events. More information about excluding NetBackup files and folders is available. https://support.cohesity.com/s/article/article-100004864
