The XenApp and XenDesktop 7.15 Long Term Service Release (LTSR) includes new versions of the Windows VDAs and new versions of several XenApp and XenDesktop core components. You can:
Use the ISO for this release to install or upgrade all the core components and Virtual Delivery Agents. Installing or upgrading to the latest version allows you to use all the latest features.
If you have a XenApp or XenDesktop deployment, and aren't ready to upgrade your core components, you can still use several of the latest HDX features by installing (or upgrading to) a new VDA. Upgrading only the VDAs is often helpful when you want to test enhancements in a non-production environment.
For instructions, see Prepare to install or Upgrade a deployment.
The XenApp and XenDesktop download pages for this release also include updated versions of the following software. For more information on the features and installation instructions, see the component's documentation.
For an overview of features that have been added since the XenApp and XenDesktop 7.6 LTSR release, see https://www.citrix.com/content/dam/citrix/en_us/documents/data-sheet/xenapp-xendesktop-715-ltsr-feature-summary-comparison-to-76-ltsr.pdf.
The product release also includes the following new, modified, and enhanced features since XenApp and XenDesktop 7.14.1.
Most supported Windows editions come with Microsoft Media Foundation already installed. If the machine on which you're installing a VDA does not have Media Foundation (such as N editions), several multimedia features will not be installed and will not work. You can acknowledge the limitation, or end the VDA installation and restart it later, after installing Media Foundation. In the graphical interface, this choice is offered in a message. In the command line, you can use the /no_mediafoundation_ack option to acknowledge the limitation.
After migrating a XenApp 6.5 farm, you can upgrade a XenApp 6.5 worker to a new VDA. Previously, running the XenApp and XenDesktop installer on the worker server automatically removed the XenApp 6.5 software and then installed the new VDA. Now, you first remove HRP7 and the XenApp 6.5 software from the server., using separate processes. Then, you install the new VDA. For details, see Upgrade a XenApp 6.5 worker to a new VDA.
When using Microsoft System Center Virtual Machine Manager to provide VMs, you can now use Machine Creation Services (MCS) to provision generation 2 VMs.
During a new installation of XenApp and XenDesktop, Local Host Cache is enabled by default. Connection leasing is disabled by default.
After an upgrade, the Local Host Cache setting is unchanged. For example, if Local Host Cache was enabled in the earlier version, it remains enabled in the upgraded version. If Local Host Cache was disabled (or not supported) in the earlier version, it remains disabled in the upgraded version.
Application Failure monitoring. Director extends the Trends view with the Application Failures tab to display historical failures associated with published applications. You can see faults and errors that have occurred while launching or running of a selected application or process during a selected time period. This information enables you to comprehend and troubleshoot application-specific issues. For more information, see Historical application failure monitoring in Troubleshoot applications.
By default, failures of applications hosted on Server OS VDAs are monitored. You can modify the monitoring settings through the Monitoring Group Policies: Enable monitoring of application failures, Enable monitoring of application failures on Desktop OS VDAs, and List of applications excluded from failure monitoring. For more information, see Policies for application failure monitoring in Monitoring policy settings.
This feature requires Delivery Controller(s) and VDAs version 7.15 or later. Desktop OS VDAs of Windows Vista or later, and Server OS VDAs of Windows Server 2008 or later are supported.
After upgrading your VDAs from version 7.9, 7.11, 7.12, 7.13, or 7.14 you do not need to update the machine catalog's functional level. The default (7.9 (or newer ...)) remains the current functional level. For information, see VDA versions and functional levels.
Load balancing for Session Recording: This experimental feature, present in XenApp and XenDesktop 7.14, is not included in this release.
How do I deploy 7.15 LTSR from scratch?
You can set up a brand-new XenApp or XenDesktop environment using the 7.15 LTSR metainstaller.* Before you do that, we recommend that you familiarize yourself with the product:
Read the XenApp and XenDesktop 7.15 Long Term Service Release documentation and pay close attention to the Technical overview, Install and configure, and Secure sections before you start planning your deployment. Make sure your setup meets the system requirements for all components. Follow Install and configure for deployment instructions.
* Note: Provisioning Services and Session Recording are available as separate downloads and installers.
What do I update?
XenApp and XenDesktop 7.15 LTSR provides updates to all baseline components of 7.6 LTSR. Remember: Citrix recommends that you update all LTSR components of your deployment to 7.15 LTSR. For example: If Provisioning Services is part of your LTSR deployment, update the Provisioning Services component. If Provisioning Services is not part of your deployment, you do not need to install or update it.
Since the original 7.6 LTSR release, we have added a metainstaller that lets you update the existing components of your LTSR environment from a unified interface. Following the Upgrade instructions, use the metainstaller to update the LTSR components of your deployment.

When you use the full-product installer to deploy or upgrade XenApp or XenDesktop components, anonymous information about the installation process is gathered and stored on the machine where you are installing/upgrading the component. This data is used to help Citrix improve its customers' installation experiences. For more information, see http://more.citrix.com/XD-INSTALLER.
The XenApp 6.5 migration process helps you more efficiently and quickly transition from a XenApp 6.5 farm to a Site running XenApp 7.15 LTSR (or a later supported release). This is helpful in deployments that contain large numbers of applications and Citrix group policies, lowering the risk of inadvertently introducing errors when manually moving applications and Citrix group policies to the new XenApp Site.
After you install the XenApp 7.15 LTSR core components and create a Site, the migration process follows this sequence:
Reconfigure the new Site as needed, and then test it.
For more information, see Migrate XenApp 6.x.
