Depending on the product versions you are using, additional configuration might be required for your Citrix-Workspace ONE Access integration after a Workspace ONE Access upgrade or Citrix upgrade. If you upgrade from Citrix 6.5 to 7.x or later, you must reconfigure the integration with Workspace ONE Access, including setting up a new virtual apps collection in the Workspace ONE Access console.
To upgrade Integration Broker, you must uninstall the older version and then install the new version.
To reinstall Citrix Receiver, see the Citrix documentation.
