Here’s a step by step upgrade guide for upgrading the Citrix License Server to version 11.10. This guide is written based on a Windows 2008 R2 server.
Go to the Citrix download page and logon with your Citrix ID and download the latest version of the installation files here.
Important: Before starting the upgrade it is always recommended that you have a backup of your license files and server. You can find the license files in the installation directory and then the “MyFiles” folder.
You can check which version of the License Server you have running now by starting the License Server webpage and going to the “Administration” button and logon. You now see the following screenshot (figure 1) which shows the version number.
Start the CTX_Licensing installer package on the License Server and select “Upgrade” (Figure 2).
If presented with the question to reboot the server because certain files are in use (figure 3) click “OK” to continue the installation.
The installation is started now (Figure 4) and wait until the installation completes. Select “Finish” to end the installation (Figure 5). Reboot the server manually when presented earlier with the question to reboot the server (Figure 3), otherwise restart the License Server service and go to the License Server webpage.
Go to the “Administration” button on the upper right corner of the screen and logon. After the logon you’ll be presented with the “System Information” page as shown below in figure 6. You now see the new version and build number of your License Server.
Good luck with the upgrade.
