Upgrade existing OPC UA configurations

Upgrade existing OPC UA configurations when upgrading OT Intelligence deployment

When you upgrade a Splunk Edge Hub device with an existing OPC UA configuration to Splunk Edge OS versions 2.4.0 or higher and Splunk OT Intelligence versions 4.12.0 and higher for the first time, you must sync the OPC UA configuration between the device and application. To perform this task, see the following steps:
  1. Download the existing OPC UA configuration from the Edge Hub advanced settings page. See Download a configuration file and upload it to another Splunk Edge Hub device to download a configuration file.
  2. Upload the existing configuration in the Edge Manager page.
  3. Select Save.
Optionally, you can upload your deployment's existing configuration to a device profile. For more information, see the Configure multiple Splunk Edge Hub devices using device profiles topic in this manual. Then, apply the profile to the devices where you want to use the OPC UA protocol.
