Upgrading the NVG Software

The Nortel VPN Gateway (NVG) software image is the executable code running on the VPN Gateway. A version of the image ships with the VPN Gateway, and comes pre-installed on the device. As new versions of the image are released, you can upgrade the software running on your VPN Gateway. Before upgrading, check the accompanying release notes for any specific actions to take for the particular software upgrade package or install image.

There are two types of upgrades:

•Minor release upgrade: This is typically a bug fix release. Usually this kind of upgrade can be done without the VPN Gateway rebooting. Thus, the normal operation and traffic flow is maintained. All configuration data is retained. When performing a minor upgrade, you should connect to the Management IP address of the cluster you want to upgrade.

•Major release upgrade: This kind of release may contain both

bug fixes as well as feature enhancements. The VPN Gateway may automatically reboot after a major upgrade, because the operating system may have been enhanced with new features. All configuration data is retained. When performing a major upgrade, you should connect to the Management IP address of the cluster you want to upgrade.

•Upgrading from software version 2.0 to software version 3.0.7: This upgrade needs to be performed in two steps, due to the new database format and software management introduced in version 3.0.7. The procedures are described in detail in "Upgrading iSD-SSL Software from Version 2.0.x to Version 3.x"

Upgrading the software on your VPN Gateway requires the following:

•Loading the new software upgrade package or install image onto a FTP/SCP/SFTP server on your network.

•Downloading the new software from the FTP/SCP/SFTP server to your VPN Gateway.
