You can find installation instructions for App Controller in Citrix eDocs at Installing App Controller 2.8.
You can upgrade from AppController 2.5, or 2.6 to App Controller 2.8. Upgrades from AppController versions before 2.5 are not supported.
Before you start the upgrade, do the following:
If you do not have an active network connection to Active Directory, the upgrade fails and reverts back to the previous version.
If your configuration is large, the upload might take several minutes. Do not interrupt the upgrade process before it is complete.
When the upgrade file successfully uploads, you receive a prompt to restart App Controller. If you choose to restart App Controller at a later time, you need to restart by using the command-line console.
