Changing From Policy to Classic Mode

This section describes how to change from Policy mode (SonicOS) to Classic mode (SonicOS) on an existing NSv deployment. After this change, all of the current configuration settings will be lost and the NSv will reboot with factory default settings. A warning to this effect is shown in the popup screen when you click the CLASSIC button.

To change from Policy mode to Classic mode

1. Navigate to the NETWORK > Firewall > Advanced page.
2. On the Settings screen next to Security Services Enforcements, click the CLASSIC button.

3. Read the popup notifications.

   

4. Click OK to proceed with the mode change or click Cancel to cancel the mode change.

   The NSv reboots and comes up in Classic mode.

5. Log into the NSv using the default credentials, admin / password.
6. Configure the network settings to allow your NSv to connect to your local network and to the internet for access to MySonicWall and the SonicWall licensing server. For more information, refer to the NSv Series 7.0 Getting Started Guide for your platform (Azure, AWS, VMware, Hyper-V or KVM). The NSv Getting Started guides are available on the SonicWall technical documentation portal at NSv 7.0 Getting Started Guides.
7. Register the NSv to enable full functionality. The Register Device button is available on the HOME | Dashboard > System pages.

At this point your can manually reconfigure the NSv or import a configuration settings file previously exported from one of the following:

• An NSv running SonicOS 7 (in Classic mode)
• An NSv running SonicOS 6.5.4.v
