All other services will be decommissioned immediately. For example, if it was a Recording service, recording will be stopped immediately, and ISS Client won’t be able to access the recorded video on the decommissioned Recording service. The recorded data will be preserved in the decommissioned Recording service. If you have a backup of iexp file, you may be able to regain the access to the recorded video, you need to re-register it to the Admin service, and then reload iexp file to it.
