How Machine Moves in Domains are Reflected in Discovery
When a machine is moved to a new OU in the domain, the effect it has in Discovery depends on the policies selected using the Discovery > Domains > Domain Watch > Policies > OU/Containers or Computers. Discovery monitoring of a member machine in the domain depends on whether its policy is set to "included" or "excluded" in both the source OU location and the target OU location.
Assuming the Include New Computers checkbox is checked in the target location:
From Included to Included - The machine ID account hierarchy is changed to match the new location in the domain hierarchy.
From Included to Excluded - The machine ID account hierarchy is not changed. The VSA must move the machine ID manually using Agent > Change Group.
From Excluded to Included - A new "empty" machine ID account hierarchy is created, matching the new location in the domain hierarchy. The VSA user can choose to merge the old machine ID account with the newly created machine ID account using the Domains > Computers > Synchronize Machines button.
From Excluded to Excluded - No change is made in the VSA.
