Before you upgrade a XenDesktop 5 Site, familiarize yourself with the new concepts and components that require upgrading and their versions, and the sequence for a successful upgrade.
New concepts and features
Compared to previous versions, XenDesktop 7.x has many new features and introduces new concepts.
There is no XenApp to XenDesktop upgrade. Citrix will support customers in their migration from XenApp 6.5 to XenDesktop in a future release and plans to release tools and or scripts to assist in this transition.
The Studio management and Director can monitor and manage only XenDesktop 7.x and XenApp 7.5 sites. The monitoring and management tools do not support past versions of XenDesktop or XenApp.
Citrix recommends that if you continue running deployments of past versions of XenApp or XenDesktop, you run them in parallel with the XenDesktop 7.x site and continue running the management consoles with each release for that site.
For example, in a mixed environment, to continue using Desktop Director 2.1 to monitor XenApp 6.5, ensure that Desktop Director 2.1 is installed on a separate server from Director 7.
Citrix recommends that you use StoreFront to aggregate applications and desktops from the different versions of XenApp and XenDesktop. For details, see the Storefront documentation.
XenDesktop Express Edition
You cannot upgrade from the XenDesktop Express Edition. You must obtain and install a license for VDI, Enterprise, or Platinum edition before upgrading.

You can upgrade these VDA versions to XenDesktop 7 Virtual Delivery Agents:
The installer upgrades all agents and existing MSIs (Windows installer packages) on the existing VDA.
Unlike previous VDA releases, you can only upgrade VDAs through the installer. You cannot upgrade to XenDesktop 7 using MSIs.
Unsupported features for VDAs running Windows 7 with 5.6 Feature Pack 1
VDAs running Windows 7 with 5.6 Feature Pack 1 do not support the following features:
VDAs installed on Windows XP or Windows Vista
Some XenDesktop 7 features are not supported on Windows XP or Windows Vista. If the installer detects a VDA running on a Windows XP or Windows Vista machine, it launches a different installer that updates to the latest VDA version that is supported on Windows XP or Windows Vista. Although these machines and their Machine Catalogs and Delivery Groups cannot use all XenDesktop 7 features, they can run in the XenDesktop 7 Site.
Unsupported features for VDAs installed on Windows XP or Windows Vista

You can upgrade the following Controller versions:

The installer also upgrades the following components:
Components that require separate upgrade
You need to upgrade the following components outside of the in-place upgrade process:
After upgrading all components, you can optionally use Studio to upgrade Machine Catalogs and Delivery Groups that included machines running earlier VDA versions or Windows XP and Windows Vista operating systems. For detailed information, see Upgrade a machine catalog and Upgrade a Delivery Group.
