Chapter 12 Upgrading
Upgrading Engines Locally
It is also possible to upgrade the engines on the engine command line as described in this
section. Upgrading locally requires a physical connection to the engine using a monitor and
keyboard or a serial cable.
During an IPS Cluster, Layer 2 Firewall Cluster, or Master Engine cluster upgrade, it is possible
for the upgraded nodes to be online and operational side by side with the older version nodes.
However, you must upgrade all the nodes to the same version as soon as possible, as
prolonged use with mismatched versions is not supported.
Upgrading From an Engine Installation DVD
You can upgrade the engines to the latest version from a DVD that was shipped to you, or from
a DVD that you have created from an .iso image that you downloaded from the McAfee web site.
 To upgrade the engine from an engine installation DVD
1. Log in to the node as
root with the password you set for the engine (you can set the
password through the Management Client).
2. Insert the DVD into the engine’s DVD drive.
3. Reboot the node from the DVD with the command
reboot (recommended) or by cycling the
power (if you cannot log in). You are promoted to select the upgrade type.
4. Enter
1 to upgrade the existing installation and press Enter to continue. The upgrade
process starts.
5. When the process is finished, eject the DVD and press Enter to reboot.
•If the Engine Configuration Wizard opens, configure the engine in the same way as after
the first installation. See Configuring the Engine in the Engine Configuration Wizard
(page 103) for instructions.
6. When the upgrade is finished, right-click the node in the Management Client and select
Commands→Go Online. A confirmation dialog opens.
7. (Optional) Enter an Audit Comment to be shown in the audit log entry that is generated
when you send the command to the engine.
8. Click Yes.
If you are upgrading an IPS Cluster, Layer 2 Firewall Cluster, or Master Engine cluster, we
recommend beginning the upgrade on the next node only when the upgraded node is back
online.
