FortiManager upgraded before SD-WAN Orchestrator MEA

If SD-WAN Orchestrator was enabled in FortiManager 6.4.1, you can no longer access it in the FortiManager GUI if you upgrade FortiManager to 6.4.2 before you upgrade SD-WAN Orchestrator MEA to 6.4.1 r2.

To workaround this issue, run the following CLI command to manually trigger an update of SD-WAN Orchestrator MEA to 6.4.1 r2:

diagnose docker upgrade sdwancontroller
