Upgrading the HA cluster for FortiOS 3.0
The following procedure will help you upgrade a FortiOS 2.80 HA cluster to
FortiOS 3.0.
You can use either the web-based manager or the execute restore image
CLI command and a TFTP server to upgrade the cluster.
To upgrade the cluster
1 Backup the configurations of the primary unit. See “Backing up your configuration”
on page 33 .
2 Install the firmware image on the primary unit.
This may take a few minutes since the primary unit will upgrade the subordinate
units as well. The FortiGate units in the cluster will reboot once or twice during the
upgrade.
SNMP MIBs and traps changes
In FortiOS 3.0 the trap file is combined into the MIB file - there is only one MIB file
to download and install to your SNMP management system.
SNMP traps and variables that used hyphens (for example xxx-yyy) have dropped
the hyphen and capitalized the second term (xxxYyy).
The v3.0 MIB file also has more in-depth descriptions, and supports models. To
see these changes, contact Fortinet technical support to obtain the MIB file.
