Downgrading - Fortinet FortiDDoS Series Release Notes

Downgrading

Downgrading
Use the following instructions to downgrade, if necessary, from FortiDDoS 5.3.0 or earlier releases.
Note the following:
Downgrading returns the system to factory default with no user configuration. If you do not have a
l
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.
Downgrades below 4.1.12 are NOT recommended for bug and security reasons. If you need to downgrade
l
below 4.1.12 you may need to alter your current configuration, removing all NTP configurations and removing
multiple remote syslog servers if configured. Please contact Fortinet Support if you need to downgrade below
4.1.12.
When downgrading there may be no default IP assigned to the Management 1 port. This will need to be set via CLI.
l
We do not recommend downgrading to releases earlier than 4.2.3.
