Configuration settings import is not supported from the SonicWall physical appliances to the NSv Series.
SonicWallNSv supports the vmxnet3 VMware Network Adapter Type. Exactly eight virtual network interfaces (vNICs) are supported on each NSv platform. Adding and removing interfaces is supported, but the total must stay within the range of two to eight.
To configure Virtual Interfaces in NSv, map the NSv parent interface for the virtual interface to a port group with the VLAN ID 4095 (Trunk Port). NSv treats a port group with VLAN 4095 as a Trunk Port.
