Mount the ISO or install media and run the setup. The installer should detect that you already have the Historian present.
Install Application Server and InTouch (verify that Historian should already be selected for upgrade)
You may need to stop the services if they are running. If that doesn’t work you may have to shutdown and disable the Historian:
Launch and run configurator after the installer completes
Make sure Historian Server has a green check next to it. You do not need to configure the extensions.
Reboot the machine and then verify that Historian starts back up and is the correct (upgraded version)
