The VMware® Horizon Workspace™ upgrade guide describes how to upgrade from version 1.5 to 1.8. If you have version 1.5 of Horizon Workspace and you would rather perform a fresh installation of Horizon Workspace 1.8, see Installing and Configuring Horizon Workspace Guide. Remember that a new installation will not preserve your existing configurations.
The update procedure requires connectivity to an update website. By default, Horizon Workspace uses the VMware website and requires Internet connectivity. See Prepare to Upgrade to Horizon Workspace 1.8 for prerequisites.
To learn how to use and maintain your updated Horizon Workspace instance, see the Horizon Workspace Administrator's Guide.
