Client versions in the network must be 9.4.0 or later. To upgrade from Trellix DLP Endpoint client version 9.3.x, see KB85478. To upgrade policies, incidents, or operational events to work with the current Trellix DLP extension, use the DLP Policy Conversion, DLP incident migration, and DLP operational events migration server tasks.
