Instructions for updating Messaging Gateway to a later software release without internet access.
The Messaging Gateway (SMG) software can up updated without connecting to the internet using the command line 'update localinstall' command. The ISO file will need to be hosted on an HTTP or SCP server to which SMG can connect to download the ISO image.
Download the SMG ISO image from FileConnect or through your MySymantec Portal. (https://mysymantec.symantec.com)
Place the ISO file on local web server (HTTP).
Log in as 'admin' to the SMG command line interface (CLI) via ssh.
Messaging Gateway will download the iso file and run the software update process as if it were downloading the packages from the internet. Following the update, the iso and temporary files will be removed from SMG to conserve disk space.
Please see HOWTO92661 for details on the command line update command and TECH88414 for software update best practices.
