This will allow models to be created with a family of Hardware regardless of what family comes from discovery. This will then allow assets to be created with a family of Hardware and a class of Reconciliation. You can then go back and use the model 'Change Model Asset Family' wizard to update the model and mass update the associated assets to the desired family and class.
Note: Failures may occur if some of the discovered data does not pre-exist in APM e.g. Operating System and Company.
