Requirements for Virtual Switch Migration During Upgrade

The AOS upgrade process initiates the virtual switch migration. The virtual switch migration is successful only when certain requirements are fulfilled. Before you upgrade to AOS, read the Virtual Switch Migration Requirements in the Virtual Switch Requirements topic in the AHV Administration Guide.
