VNA models in Spectrum are deleted and recreated after enabling and disabling the VNA integration.
Environment
Spectrum 10.2.3 and below
Cause
Before enabling VNA Integration, if ACI models are discovered in 10.2.x and then the VNA Integration is enabled and disabled, the ACI Models are getting deleted and recreated.
Resolution
There is a database change in Spectrum 10.3.0 which addresses this issue. No fix available for 10.2.x as this database change can not be back ported.
