This article explains about the steps to Install a New SONICOSX 7 NSV Version in SafeMode.
In SafeMode, you can upload a new SonicOS/X SWI image and apply it to the NSv virtual machine. The SafeMode web management interface is used to perform an upgrade, rather than SafeMode in the NSv management console. When viewing the NSv management console in SafeMode, the URL for the SafeMode web interface is displayed at the bottom of the screen.
TIP: In SafeMode, the web management interface is only available by way of http (not https).
SWI files are used to upgrade SonicOS/X. You can download the latest SWI image file from MySonicWall.
