You can use the NewMM.pl post-installation script to automatically convert existing models of various model types to newly-supported model types while preserving many key attributes, relationships, and other elements. For example, if you have previously modeled Cisco Catalyst 4500 devices as GnSNMPDev in SPECTRUM, these models can be converted to use the functionality of the Catalyst 4500 Management Module. Models based on model types introduced in SPECTRUM 6.0.0 and later versions are eligible for conversion.
Further information can be found in the SPECTRUM Installation Guide (doc 5136.pdf)
