Use the Manage Controllers task to add and remove from stores resources provided by XenDesktop, XenApp, and App Controller, and to modify the details of the servers providing these resources.
In multiple server deployments, use only one server at a time to make changes to the configuration of the server group. Ensure that the Citrix StoreFront management console is not running on any of the other servers in the deployment. Once complete, propagate your configuration changes to the server group
so that the other servers in the deployment are updated.
