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.x).
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).
Important: Upgrades are not supported for License Server VPX.
