Upgrade PI System Connector

If you are upgrading PI System Connector, follow the installation procedure as described in Install PI System Connector and be aware of the following:

• If the current connector uses PI Data Collection Manager version 2.4 or earlier, you must install PI Data Collection Manager version 2.5 before upgrading to a new version of the connector. For information on installation of PI Data Collection Manager version 2.5 or later, see the PI Connector Administration user guide.

• During installation, it is possible to specify a different log on user to run the connector service.

  Note: 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 PI Servers after the upgrade.
