If you are upgrading your connector, you need to follow the installation procedure as described in Install the connector and be aware of the following:

  • If your current connector uses PI Data Collection Manager version 2.2 or earlier, you must install PI Data Collection Manager version 2.3 before upgrading to a new version of the connector. For information on installation of PI Data Collection Manager version 2.3 or later, see the PI Connector Administration 2.3 or later user guides.

  • When specifying the user name in the Windows Service Configuration window during installation, it allows you to specify a log on user different than the user already configured to run the connector service.

    Caution: If you change the log on user and the connector already has data sources configured, the connector might not be able to communicate with the server after the upgrade.
