VDOM link and policy configuration is lost after upgrading if VDOM and VDOM link have the same name
Affected versions:
- FortiOS 6.4.9 and later
- FortiOS 7.0.6 and later
- FortiOS 7.2.0 and later
When upgrading to one of the affected versions, there is a check within the set vdom-links
function that rejects vdom-links
that have the same name as a VDOM. Without the check, the FortiGate will have a kernel panic upon bootup during the upgrade step.
A workaround is to rename the vdom-links
prior to upgrading, so that they are different from the VDOMs.
