Where: Navigator > Resources > Connectors
Select the connector you want to upgrade, right-click to bring up the context menu, and choose Send Command > Upgrade > Upgrade.
This opens a Command Parameters dialog.
Provide the following information in the dialog.
Version - The Version field provides a drop-down menu showing the connector versions available on this Manager. Choose the Version number of the connector to which you want to upgrade.
Event wait (sec) - Number of seconds the upgrade process waits for the first event from the device after the new, upgraded connector is started. If no events are received from the device within the specified time frame, the upgrade is considered "failed" and the old connector is launched.
This optional check is an additional safeguard against upgrade failures. For example, the connector binaries may have been upgraded successfully, but the new version may have problems communicating with the device. In that case, this check assumes that the upgrade failed and bring back the old connector.
If the Event wait (sec) value is 0 (the default), then the upgrade does not perform this check.
Click OK to close the dialog and start the upgrade.
As the upgrade proceeds, the connector shows as down and then running again in the resource tree. Status messages on the ArcSight Console indicate whether the upgrade succeeds or fails. You can check the logs for the connector to determine if the upgrade succeeded. (Send Command > Tech Support > Get 'agent.properties' and Get Upgrade Logs.)
