Upgrade a Citrix ADC standalone appliance
Before upgrading the system software, make sure that you read theBefore you beginsection and complete the necessary prerequisites such as backing up the necessary files and downloading the Citrix ADC firmware.
Note
Starting with release 12.1, 64-bit Citrix ADC MPX and VPX images are supported, along with 32-bit images. For more information, see the Citrix Downloads site.
Upgrade a Citrix ADC standalone appliance by using the GUI
Follow these steps to upgrade a standalone Citrix ADC to release 12.1 by using the GUI.
- In a web browser, type the IP address of the Citrix ADC, for example
http://10.102.29.50
. - In User Name and Password, type the administrator credentials (nsroot/nsroot) and then clickLog On.
Navigate toSystemand clickSystem Upgrade.
From theChoose Filedrop-down menu choose the appropriate option:LocalorAppliance. If you want to use the Appliance option, the firmware needs to be uploaded to the Citrix ADC first. You can use any file tranfer method such as WinSCP to upload the Citrix ADC firmware to the appliance.
Select the correct file and clickUpgrade.
Follow the instructions to upgrade the software.
- When prompted, selectReboot.
After the upgrade, close all browser instances and clear your computer’s cache before accessing the appliance.
Upgrade a Citrix ADC standalone appliance by using the CLI
Follow these steps to upgrade a standalone Citrix ADC to release 12.1 by using the CLI:
In the following procedure,
and
represent the release version you are upgrading to, and
represents the build number that you are upgrading to. The procedure includes optional steps to avoid losing any updates that are pushed to the /etc directory during the upgrade.
Use an SSH client, such as PuTTy, to open an SSH connection to the appliance.
Log on to the appliance by using the administrator credentials. Save the running configuration. At the prompt, type:
save config
Switch to the shell prompt by running the following command:
shell
Create a copy of the ns.conf file. At the shell prompt, type:
cd /nsconfig
cp ns.conf ns.conf.NS
You should backup the configuration file to another computer.
(Optional) If you have modified some of the following files in the /etc directory, and copied them to /nsconfig to maintain persistency, any updates that are pushed to the /etc directory during the upgrade might be lost:
- ttys
- resolv.conf
- sshd_config
- host.conf
- newsyslog.conf
- host.conf
- httpd . conf
- rc.conf
- syslog.conf
- crontab
- monitrc
To avoid losing these updates, create a /var/nsconfig_backup directory, and move the customized files to this directory. That is, move any files that you modified in /etc directory and copied to /nsconfig by running the following command:
cp /nsconfig/
/var/nsconfig_backup Example:
cp /nsconfig/syslog.conf /var/nsconfig_backup
Create a location for the installation package. At the shell prompt type:
cd /var/nsinstall
cd
Note:
If the desired release number directory is not present, create one using the following command:
mkdir
Example:
mkdir 13.0
mkdir build_
cd build_
Copy the already downloaded Citrix ADC firmware to the build directory that you have created in the above step, by using any file transferring method such as WinSCP. See theBefore You Beginsection for more information about downloading the Citrix ADC firmware.
Extract the contents of the installation package. Example:
tar –xvzf build-12.1-32.2_nc_64.tgz
tar –xvzf build-12.1-32.2_nc_32.tgz
Run the installns script to install the new version of the system software.
./installns
When prompted, restart the Citrix ADC.
(Optionally) If you’ve created a copy of the ns.conf file in the Before You Begin section, do the following:
- Manually compare the files in /var/nsconfig_backup and /etc and make appropriate changes in /etc.
- To maintain persistency, move the updated files in /etc to /nsconfig.
- Restart the appliance to put the changes into effect.
