Upgrade firmware via CLI

Before you run the install script, the files must be extracted and placed on the appliance. Use the following command to uncompress the bundle located, for instance, in /var/nsinstall/build-11.0-64.34_nc/:

tar -zxvf <archive_filename>.tgz

ns_install_01

The run the following command to initiate the upgrade process:

./installns

ns_install_02

NetScaler device/instance automatically alert Citrix support on detecting
critical errors and/or potential failures, before it impacts your network.
You can also configure this feature anytime using the command line interface

After the upgrade has been successfully completed simply reboot your NetScaler by entering Y and pressing <Enter>. After abouot 90 seconds the NetScaler will be back online and accessible through your browser. Log back in and verify whether the upgrade has been completed successfully by checking your firmware version and license status:

In case you get bogged by the newly added feature called CUXIP (Citrix User Experience Improvement Program), you’re free to chose whether you want to enable it or not.

ns_install_04

After that verify the NetScaler Gateway’s functionality by logging in to your vServer’s public Gateway and launching any published resources.
