NetScaler VPX – upgrade firmware

I am fairly new to NetScaler to I tried to upgrade the software via CLI. This is what I if done.

1. Download the upgrade firmware via MyCitrix.com
2. Backup the configuration
3. Upgrade the software to the NetScaler appliance (I used pscp.exe on a Windows machine to upload the software to the directory /var/nsinstall/11.0/63.16. I created the directories 11.0/63.16 before uploading the firmware)
4. Untar the software
5. Install the software (relax and take your time)
6. Reboot the appliance
7. Verify the upgrade (show version)

When everything goes according to plan, you would see the following output:

root@netscaler# tar zxvf build-11.0-63.16_nc.tgz
x .ns.version
x ns-11.0-63.16.gz
x ns-11.0-63.16.sha2
…….
x libvpath_if.so
x Citrix_Netscaler_InBuilt_GeoIP_DB.csv.gz

root@netscaler# ./installns

installns: [94606]: END_TIME 1444387469 Fri Oct 9 12:44:29 2015

Installation has completed.
