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.
