In this article:
Ensure that you download and use the 7.14.1 XenApp and XenDesktop ISO and VDAs. (The file name contains the version number.) Do not use the original 7.14 versions.
You can upgrade certain deployments to newer versions without having to first set up new machines or Sites. That process is called an in-place upgrade. See Upgrade for a list of the versions you can upgrade.
You can also use the current XenApp installer to upgrade a XenApp 6.5 worker server to a current VDA for Windows Server OS. This is a supplementary activity to migrating XenApp 6.5. See Upgrade a XenApp 6.5 worker to a new VDA for Windows Server OS.
To start an upgrade, you run the installer from the new version to upgrade previously installed core components (Delivery Controller, Citrix Studio, Citrix Director, Citrix License Server) and VDAs. Then you upgrade the databases and the Site.
Be sure to review all the information in this article before beginning the upgrade.
The following diagram summarizes the upgrade sequence. Details are provided in Upgrade procedure below. For example, if you have more than one core component installed on a server, running the installer on that machine will upgrade all components that have new versions. You might want to upgrade the VDA used in a master image, and then update the image. Then, update the catalog that uses that image and the Delivery Group that uses that catalog. Details also cover how to upgrade the Site databases and the Site automatically or manually.
Using the product installer, you can upgrade:
Using the guidance in the feature/product documentation, upgrade the following if needed:
The following limitations apply to upgrades:
Selective component install
If you install or upgrade any components to the new version but choose not to upgrade other components (on different machines) that require upgrade, Studio will remind you. For example, let's say an upgrade includes new versions of the Controller and Studio. You upgrade the Controller but you do not run the installer on the machine where Studio is installed. Studio will not let you continue to manage the Site until you upgrade Studio.
You do not have to upgrade VDAs, but Citrix recommends upgrading all VDAs to enable you to use all available features.
XenApp version earlier than 7.5
You cannot upgrade from a XenApp version earlier than 7.5. You can migrate from XenApp 6.x; see Migrate XenApp 6.x.
Although you cannot upgrade a XenApp 6.5 farm, you can replace the XenApp 6.5 software on a Windows Server 2008 R2 machine with a current VDA for Server OS. See Upgrade a XenApp 6.5 worker to a new VDA.
XenDesktop version earlier than 5.6
You cannot upgrade from a XenDesktop version earlier than 5.6.
XenDesktop Express Edition
You cannot upgrade XenDesktop Express edition. Obtain and install a license for a currently supported edition, and then upgrade it.
Early Release or Technology Preview versions
You cannot upgrade from a XenApp or XenDesktop Early Release or Technology Preview version.
If you have VDAs installed on Windows XP or Windows Vista machines, see VDAs on machines running Windows XP or Windows Vista.
When you upgrade from an earlier 7.x version, you do not choose or specify the product (XenApp or XenDesktop) that was set during the initial installation.
If you must continue to run earlier version Sites and current version Sites, see Mixed environment considerations.
Before beginning an upgrade:
Decide which installer and interface to use
Use the full-product installer from the XenApp or XenDesktop ISO to upgrade core components. You can upgrade VDAs using the full-product installer or one of the standalone VDA installers. All installers offer graphical and command line interfaces. For more information, see Installers.
You cannot upgrade by importing or migrating data from a version that can be upgraded. (Note: Some much earlier versions must be migrated instead of upgraded; see Upgrade and migrate for a list of which versions can be upgraded.)
If you originally installed a desktop VDA with the VDAWorkstationCoreSetup.exe installer, Citrix recommends using that installer to upgrade it. If you use the full-product VDA installer or the VDAWorkstationSetup.exe installer to upgrade the VDA, the components that were originally excluded might be be installed, unless you expressly omit/exclude them from the upgrade.
For example, if you installed a version 7.13 VDA using VDAWorkstationCoreSetup.exe, and then used the full-product installer to upgrade that VDA to version 7.14, the components that were excluded from the original installation (such as Profile management or Personal vDisk) might be installed during the upgrade, if you accept the default settings or do not use the /exclude command-line option.
Check your Site's health
Ensure the Site is in a stable and functional state before starting an upgrade. If a Site has issues, upgrading will not fix them, and can leave the Site in a complex state that is difficult to recover from. To test the Site, select the Site entry in the Studio navigation pane. In the Site configuration portion of the middle pane, click Test site.
Back up the Site, monitoring, and Configuration Logging databases
Follow the instructions in CTX135207. If any issues are discovered after the upgrade, you can restore the backup.
Optionally, back up templates and upgrade hypervisors, if needed.
Complete any other preparation tasks dictated by your business continuity plan.
Ensure your Citrix licensing is up to date
Before upgrading the Citrix License Server, be sure your Subscription Advantage date is valid for the new product version. If you are upgrading from an earlier 7.x product version, the date must be at least 2017.0517.
Close applications and consoles
Before starting an upgrade, close all programs that might potentially cause file locks, including administration consoles and PowerShell sessions. (Restarting the machine ensures that any file locks are cleared, and that there are no Windows updates pending.)
Important: Before starting an upgrade, stop and disable any third-party monitoring agent services.
Ensure you have proper permissions
In addition to being a domain user, you must be a local administrator on the machines where you are upgrading product components.
The Site database and the Site can be upgraded automatically or manually. For an automatic database upgrade, the Studio user's permissions must include the ability to update the SQL Server database schema (for example, the db_securityadmin or db_owner database role). For details, see the Databases article. If the Studio user does not have those permissions, initiating a manual database upgrade will generate scripts. The Studio user runs some of the scripts from Studio; the database administrator runs other scripts using a tool such as SQL Server Management Studio.
When your environment contains Sites/farms with different product versions (a mixed environment), Citrix recommends using StoreFront to aggregate applications and desktops from different product versions (for example, if you have a XenDesktop 7.13 Site and a XenDesktop 7.14 Site). For details, see the StoreFront documentation.
Within each Site, Citrix recommends upgrading all components. Although you can use earlier versions of some components, all the features in the latest version might not be available. For example, although you can use current VDAs in deployments containing earlier Controller versions, new features in the current release may not be available. VDA registration issues can also occur when using non-current versions.
You cannot upgrade VDAs installed on machines running Windows XP or Windows Vista to a 7.x version. You must use VDA 5.6 FP1 with certain hotfixes; see CTX140941 for instructions. Although earlier-version VDAs will run in a 7.x Site, they cannot use many of its features, including:
Citrix recommends reimaging Windows XP and Windows Vista machines to a supported operating system version and then installing the latest VDA.
To upgrade VDAs installed on machines running Windows 8.x or Window 7 to Windows 10, Citrix recommends reimaging Windows 7 and Windows 8.x machines to Windows 10 and then installing the supported VDA for Windows 10. If reimaging is not an option, uninstall the VDA before upgrading the operating system; otherwise, the VDA will be in an unsupported state.
When you upgrade the product to a later version, Citrix recommends you upgrade all the core components and VDAs so you can access all the new and enhanced features in your edition.
In some environments, you may not be able to upgrade all VDAs to the most current version. In this scenario, when you create a machine catalog, you can specify the VDA version installed on the machines. By default, this setting specifies the latest recommended VDA version; you need to consider changing this setting only if the machine catalog contains machines with earlier VDA versions. However, mixing VDA versions in a machine catalog is not recommended.
If a machine catalog is created with the default recommended VDA version setting, and any of the machines in the catalog has an earlier VDA version installed, those machines will not be able to register with the Controller and will not work.
For more information, see VDA versions and functional levels.
To run the product installer graphical interface, log on to the machine and then insert the media or mount the ISO drive for the new release. Double-click AutoSelect. To use the command-line interface, see Install using the command line.
Step 1. If more than one core component is installed on the same server (for example, the Controller, Studio, and License Server) and several of those components have new versions available, they will all be upgraded when you run the installer on that server.
If any core components are installed on machines other than the Controller, run the installer on each of those machines. The recommended order is: License Server, StoreFront, and then Director.
Step 2. If you use Provisioning Services, upgrade the PVS servers and target devices, using the guidance in the Provisioning Services documentation.
Step 3. Run the product installer on machines containing VDAs. (See Step 12 if you use master images and Machine Creation Services.)
Step 4. Run the product installer on half of the Controllers. (This also upgrades any other core components installed on those servers.) For example, if your Site has four Controllers, run the installer on two of them.
Step 5. If Studio is installed on a different machine than one you've already upgraded, run the installer on the machine where Studio is installed.
Step 6. From the newly upgraded Studio, upgrade the Site database. For details, see Upgrade the databases and the Site.
Step 7. From the newly upgraded Studio, select Citrix Studio site-name in the navigation pane. Select the Common Tasks tab. Select Upgrade remaining Delivery Controllers.
Step 8. After completing the upgrade and confirming completion, close and then reopen Studio.
Step 9. In the Site Configuration section of the Common Tasks page, select Perform registration. Registering the Controllers makes them available to the Site.
Step 10. After you select Finish when the upgrade completes, you are offered the opportunity to enroll in the Citrix telemetry programs, which collect information about your deployment. That information is used to improve product quality, reliability, and performance.
Step 11. After upgrading components, the database, and the Site, test the newly-upgraded Site. From Studio, select Citrix Studio site-name in the navigation pane. Select the Common Tasks tab and then select Test Site. These tests were run automatically after you upgraded the database, but you can run them again at any time.
The Test Site functionality might fail for a Controller installed on Windows Server 2016, when a local SQL Server Express is used for the Site database, if the SQL Server Browser service is not started. To avoid this, complete the following tasks.
1. Enable the SQL Server Browser service (if required) and then start it.
2. Restart the SQL Server (SQLEXPRESS) service.
Step 12. If you use Machine Creation Services and want to use upgraded VDAs: After you upgrade and test the deployment, update the VDA used in the master images (if you haven't done that already). Update master images that use those VDAs. See Update or create a new master image. Then update machine catalogs that use those master images, and upgrade Delivery Groups that use those catalogs.
After upgrading the core components and VDAs, use the newly upgraded Studio to initiate an automatic or manual database and Site upgrade.
Remember: Check the Preparation section above for permission requirements.
During a database upgrade, product services are disabled. During that time, Controllers cannot broker new connections for the Site, so plan carefully.
After the database upgrade completes and product services are enabled, Studio tests the environment and configuration, and then generates an HTML report. If problems are identified, you can restore the database backup. After resolving issues, you can upgrade the database again.
Upgrade the database and Site automatically:
Launch the newly upgraded Studio. After you choose to start the Site upgrade automatically and confirm that you are ready, the database and Site upgrade proceeds.
Upgrade the database and Site manually:
Step 1. Launch the newly-upgraded Studio. After you choose to manually upgrade the Site, the wizard checks for License Server compatibility and requests confirmation. After you confirm that you have backed up the database, the wizard generates and displays the scripts and a checklist of upgrade steps.
Step 2. Run the following scripts in the order shown.
PowerShell script to be run by the Studio user on a Controller to disable product services.
SQL script to be run by the database administrator on the server containing the Site database.
SQL script to be run by the database administrator on the server containing the Monitor database.
SQL script to be run by the database administrator on the server containing the Configuration Logging database. Run this script only if this database changes (for example, after applying a hotfix).
PowerShell script to be run by the Studio user on a Controller to enable product services.
Step 3. After completing the checklist tasks. click Finish upgrade.
