Product Documentation

Each time you upgrade your Citrix product, you should also upgrade the Citrix License Server. Each time a new license server is released, it may contain better security, fixes to known issues, and so on. In some cases, new versions of the Citrix product will not work with older versions of the license server.
Note: New versions of the license server are compatible with older versions of the product.

If you are a current Citrix Subscription Advantage member, you are eligible to version upgrade to the latest release of Citrix products and upgrade your existing licenses to the license system used by these products.

Version Upgrade means the movement from any previous version of a product to the newest version of the product (for example, moving from XenDesktop 5.6 to XenDesktop 7.0).

Edition Upgrade means the purchase of a higher edition level of a product (for example, you currently have Enterprise Edition and you purchase an upgrade to Platinum Edition).

Upgrade the license server

Citrix recommends that you install the newest license server. The new license server is backward compatible and will work with older products and license files; however, new products require the newest license server to check out licenses correctly. You can install or upgrade the latest version from the Citrix Web site (Downloads page).

Upgrade your licensing components before upgrading your product, if necessary. Uninstall any versions of Citrix Licensing older than version 11.3.

For information about system requirements, see System requirements.

Note: If you installed your License Server without successfully configuring it with the post installation License Server Configuration tool, any subsequent License Server upgrades fail.

To upgrade the license server:

  1. From your license server, open the media for your product. You can also find the license components download on the Citrix Web site (Downloads page).
  2. If you do not see Setup, use Windows Explorer to open Autorun.exe.
  3. Navigate through the setup wizard screens to Citrix Licensing and follow the instructions.

Upgrade licenses for your edition

If you decide to run a higher edition of a Citrix product (for example, XenDesktop Enterprise to Platinum), you must purchase an upgrade license and add it to the license server. You will also need to change the product edition setting in the product’s user interface. Citrix recommends that you plan to change the product edition setting during a time when there are not many connections to the affected servers or that you plan to redirect connections to another computer. When you change the product edition setting, you must restart the product server for changes to take effect. See the product’s documentation for changing the edition setting. If you add the upgrade license to the license server before you set the edition to the new edition, the Citrix product stops accepting new connections.

Note: Licenses from old product editions appear on the Dashboard of the License Administration Console even though they are no longer valid. If you do not remove obsolete and/or unnecessary license allocations, you might see persistent alerts regarding the Subscription Advantage expiration dates of these licenses. You cannot turn these alerts off. The only impact of leaving obsolete license allocations on license servers is that you will continue to receive these alerts. If you want to remove the licenses, see Delete License Files.
