FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
This article describes that when upgrading FortiGates to certain FortiOS versions, configurations for VDOM links and associated policies may be lost if the VDOM link and VDOM share the same name, due to a validation check that rejects identical names and results in a critical system failure.
Scope
FortiGate v6.4.9 and later, v7.0.6 and later, v7.2.0 and later.
List all VDOMs and VDOM links on the device. Check for any naming conflicts between them:
show system vdom-link show system vdom
Any VDOM link which has the same name as VDOM, change it to something unique:
config system vdom-link edit "Finance_Link # Change from "Finance" to "Finance_Link" set name "Finance_Link" next end
Once all VDOM links have unique names, proceed with the upgrade to the desired version.
