A tool can be designed that identifies differences or gaps in coverage between network management systems without deploying both network management systems (i.e., an already deployed network management system and a comparison network management system). This “certification gap analyzer” can analyze the coverage of the current network management system in comparison with the certification of the comparison network management system and identify gaps in coverage between devices and device components (collectively referred to hereinafter as “managed objects”) certified in the different network management systems. The certification gap analyzer can present a comparison of coverage of managed objects by leveraging naming patterns of managed objects.
