This section highlights some of the operational changes that administrators should be aware of in 6.4.6.
Starting in FortiManager 6.4.6, ADOM versions are enforced. ADOM version N and N+1 are allowed, and the enforcement affects policy package installation.
For example, if you have ADOM version 6.0, and it contains a FortiGate running FortiOS 6.4, you cannot install a version 6.0 policy package to the FortiGate. The policy package installation fails with the following error message:
Device preparation failed: version mismatched,adom:6.0; dev:6.4.
Upgrading FortiManager when Management Extension Applications (MEA) are enabled may reset your System Settings to the default settings.
To prevent your System Settings from being lost, please disable all Management Extension Applications (MEA) prior to upgrading FortiManager.
FortiManager 6.4.3 and later no longer displays policy hit count information on the Policy & Objects > Policy Packages pane. However, you can view hit count information by using the Unused Policies feature and clearing the Unused Only checkbox. For more information, see the FortiManager 6.4 New Features Guide.
If Wireless Manager was enabled in FortiManager 6.4.0, you can no longer access it in the FortiManager GUI when you upgrade FortiManager to 6.4.2. When you try to access FortiWLM, you are redirected to the FortiManager dashboard.
If SD-WAN Orchestrator was enabled in FortiManager 6.4.1, you can no longer access it in the FortiManager GUI after upgrading to FortiManager 6.4.2.
To workaround this issue, run the following CLI command to manually trigger an update of SD-WAN Orchestrator to 6.4.1 r2:
diagnose docker upgrade sdwancontroller
In 6.4 ADOMs, SD-WAN member interfaces are grouped into SD-WAN zones. These zones can be imported as normalized interfaces and used in firewall policies.
Customers upgrading FortiGates from FortiOS 6.2 to 6.4 who cannot upgrade the ADOM are advised to temporarily disable SD-WAN central management until they can upgrade the ADOM to 6.4. This is to prevent FortiManager from attempting to delete the newly created SD-WAN zones on the FortiGate.
FortiManager 6.4.1 or later is the supported version to provide FortiGuard rating services to FortiGate 6.4.1 or later.
Citrix XenServer limits ramdisk to 128M by default. However the FMG-VM64-XEN image is larger than 128M. Before updating to FortiManager 6.4, increase the size of the ramdisk setting on Citrix XenServer.
- On Citrix XenServer, run the following command:
xenstore-write /mh/limits/pv-ramdisk-max-size 536,870,912
- Confirm the setting is in effect by running
limits = ""
pv-kernel-max-size = "33554432"
pv-ramdisk-max-size = "536,870,912"
boot-time = ""
- Remove the pending files left in
The ramdisk setting returns to the default value after rebooting.
Prior to using the FortiManager to push a multi-step firmware upgrade, confirm the upgrade path matches the path outlined on our support site. To confirm the path, please run:
dia fwmanager show-dev-upgrade-path <device name> <target firmware>
Alternatively, you can push one firmware step at a time.
A Hyper-V FMG-VM running on a PC with an AMD CPU may experience a kernel panic. Fortinet recommends running VMs on an Intel-based PC.
Due to known vulnerabilities in the SSLv3 protocol, FortiManager-VM64-AWS only enables TLSv1 by default. All other models enable both TLSv1 and SSLv3. If you wish to disable SSLv3 support, please run:
config system global
set ssl-protocol t1sv1
