vCenter Appliance 6.5 upgrade to 6.7 Error

I was upgrading a vCenter today, that was running on a Standalone ESXi host, that was using the free Hypervisor license.

I always uses the CLI and JSON file for upgrading vCenter servers, since it’s easy to run the upgrade multiple times, without going thru the GUI.

Bu when i did at this customer, I got this error message.

esxi00.domain.local.

Result and Log File Information…
WorkFlow log directory:

I analyzed the log files, af found that, a reference in one of them that the ESXi host did not support a feature.

So it turns out that this can not be done when using the free hypervisor license on the ESXi hosts.

The ESXi host was 6.5 Update 1 build 7388607, and have not check if this is only a problem with this version.
