Upgrading to 5.4

This table shows the upgrade path from earlier versions of the supported firmware to the latest version of FortiOS 5.4.

Upgrade Issues specific to 5.4.x

Wildcard FQDNs

FortiOS 5.2 allowed configurations to use wildcard FQDN objects in the firewall policies.  This functionality was removed starting in 5.4. If a user has a firewall running FOS 5.2 with firewall rules configured to use wildcard FQNDs, when the customer upgrades the firewall to FOS 5.4.x or later, the firewall rules using wildcard FQDNs will be deleted.  This can cause unexpected traffic to pass or be blocked.

Notice: You may notice that these tables do not exactly match the Release Notes or the Upgrade Path on the Support site. See “Divergence from the Release Notes” for an explanation.
