Downgrading FortiDDoS-CM
Note the following:
l
Downgrading returns the system to factory default with no user configuration. If you do not have a
stored backup configuration of the earlier release and must downgrade, you will need to backup your
current configuration, edit the first line to the correct destination (downgraded) firmware release, build
number and date, and restore that configuration file. If you are unsure of this step, contact Fortinet
Support.
l
When downgrading there may be no default IP assigned to the Port 1. This will need to be set via VM console after
the downgrade is complete.
