Overview :

SonicOS 7.1 introduces exciting features focused on Superior Threat Protection, Ease of Use, Enhanced Security, and improved cloud deployments with SonicCoreX-based NSv, which introduces Secure boot and virtual TPM. SonicOS 7.1 brings in NSv bootstrapping and token-based registration for mass deployment across all supported platforms.

Please note that there is no upgrade path from the existing NSv versions running SonicOS 7.0.1 firmware to SonicOS 7.1.X and above (including 7.2.x, 7.3.x, etc.).

Product And Environment:

SonicWall Virtual Platforms NSv 270, NSv 470, NSv 870

Impact :

Customers migrating from SonicOS 7.0.1 to SonicOS 7.1.X and above will be required to perform a fresh installation of the NSv on all supported platforms (KVM, Hyper-V, VMware, Azure, and AWS).

What to do :

Please follow the best practices before proceeding with the installation of the SonicOS 7.1.X and above NSv image.

• Back up the configuration from the NSv running on SonicOS version 7.0.  Check KB: How can I upgrade my SonicOS Firmware
• Ensure to back up the Certificates: Export the local certificates from 7.0.1 NSv 
  NOTE:  Only Local certificates can be exported, and CA certificates cannot be exported. 
• De-register the license on existing NSv 7.0.1, to unbind the serial number with the current NSv instance from the 'Device | Settings | Licenses' page

• Deploy a fresh NSv virtual machine, based on the latest SonicOS firmware version, for example:

Azure  - ARM template/Custom deployment or SonicWall NSv on Azure Marketplace 
AWS - SonicWall NSv on AWS Marketplace
ESXi - download OVA file from Sonicwall portal
KVM - download IMG file from Sonicwall portal
Hyper-V - download VHD file from Sonicwall portal

• Register the firewall using the Serial number and the Authentication Key.
  NOTE: If assistance is needed to unbind the existing serial number or an error like ''This firewall serial number is already registered'', please contact the SonicWall support team.  
• Import the local certificates. 
  NOTE: The CA certificate needs to be imported from the local drive.
• Import Prefs (EXP) to the newly deployed NSv running on the latest SonicOS firmware version.
