Upgrade the Operational Technology Plugin

Upgrading the Operational Technology Plugin is part of the Forescout Platform eyeSight-eyeInspect integration upgrade process. See Upgrade the eyeSight-eyeInspect Integration for the full process.

Avoid Host Duplication When Upgrading the OT Plugin

Upgrading the OT Plugin can re-trigger the duplicate-host problem if the IP Reuse Domain (IRD) mapping is not verified before the Enable host information forwarding option is enabled. To avoid this:

  1. Disable the Enable host information forwarding option. This stops host data from flowing while the mapping and plugin version are in transition.

  2. Remove hosts in eyeInspect that were sourced from eyeSight. This clears records tied to the pre-upgrade identity so they cannot collide with re-synced data.

  3. Upgrade the OT Plugin to the v3.2.1 (as described in the Step by step guide below).

    Continue with steps 4-6 below after upgrading to eyeSight version 9.1.6

  4. Verify that the IP Reuse Domain mapping is correct for every connected Command Center.

  5. If the mapping was found to be incorrect in step 4, perform a host cleanup on eyeSight as well before continuing.

  6. Re-enable the Enable host information forwarding option. Normal host sync resumes now that the mapping is verified.
