# Patch or upgrade the SMC Appliance in the SMC Client

You can use the SMC Client to patch or upgrade the SMC Appliance. In some certified environments, you must use the SMC Client to install SMC Appliance patches.

## Before you begin

In environments without Internet connectivity, you must download the SMC Appliance patch file from https://update.stonesoft.com/download/appliance/patches/, then transfer the file to a location that is accessible from the SMC Client.

Before upgrading, read the Release Notes.

Installing some SMC Appliance patches might restart the SMC Appliance. The Restart Required column in the SMC Client indicates whether the appliance must restart as part of the installation. You can use the SMC Client to install SMC Appliance patches regardless of whether the installation requires restarting the SMC Appliance.
