Citrix NetScaler provides a complete web application load balancing, acceleration, security and offload feature set in a simple virtual appliance or a physical device. Let’s see how to upgrade it to the latest version. The following procedure took place on a virtual appliance.
The latest firmware release will appear at the top of the page. Click the Release link, in our case Release 10 Build 75.7 and at the bottom of the new page click the Download button.
Save the downloaded compressed file in a folder, and download the related documentation at the Related Resources Section, named NS Documentation 10 Build 75.7 in our case. Save it in the same folder.
Next login into Netscaler GUI and goto the System Information. At the bottom of the right pane, click the Upgrade Wizard.
Click the Next button.
Then select the Upload Software and Documentation from the Local Computer.
Select the Reboot after successful installation checkbox and press Next and Finish.
The upgrade procedure will start by downloading and installing the files.

Installation is starting ...
CallHome is currently disabled. This is a new feature in 10.x that would
let this NetScaler device automatically alert Citrix support on detecting
critical errors and/or potential failures, before it impacts your network.
You can also configure this feature anytime with "enable feature ch" CLI
command or through GUI. Please see the documentation for further details.
If you enable this feature, please save the configuration after reboot.
