New in the Vancouver release

Convert IT hardware to OT devices in a bulk edit
Use the Convert to OT assets button in the All IT Hardware list to bulk edit selected IT Hardware assets and convert them to OT assets.
Convert your OT devices to IT hardware devices in a bulk edit
Use the Remove OT asset details button if you encounter OT assets that don't have an OT function and should be classified as IT hardware devices.
Preview existing OT asset records in the CMDB
Preview the records that already exist in the CMDB. You can do this before you import OT asset records from the staging table to the CMDB to avoid merging or reconciling the duplicate records.
OT Devices landing page tab
Track your OT device data with multi-site and business unit filtering by using the OT Devices landing page tab that was added to the Industrial Workspace. This landing page tab now runs in Performance Analytics.
Implementing multi-site and business unit filtering in the new OT Devices landing page tab
Filter the data shown that is based on the specific business units and sites by using the business unit and site filters in the OT Devices landing page.
Bulk Update Ruleset for Reassigning IT to OT feature
Automatically convert IT hardware into OT devices by using the Bulk Update Ruleset for Reassigning IT to OT feature.
