Can't restore VMhost config


So I'm trying to do the set-vmhostfirmware but doing it to the same 6.5 but a different revision. I'm getting the following error

PS C:\WINDOWS\system32> Set-VMHostFirmware -SourcePath C:\temp\Backup\configBundle-
Set-VMHostFirmware : 30/08/2018 09:45:26      Set-VMHostFirmware            A general system error occurred: Internal error      
At line:1 char:1
+ Set-VMHostFirmware -SourcePath C:\temp\Backup\configBundle- ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + FullyQualifiedErrorId : Client20_SystemManagementServiceImpl_RestoreVmHostFirmware_ViError,VMware.VimAutomation.ViCore.Cmdlets.Commands.Host.SetVMHostFirmware

Any ideas?

Restores must be to the same build and version of ESXi, not different - that is not supported.

So a backup from ESXi 6.5 build xxxxxx, must be restored to ESXi 6.5 build xxxxxx.

if you restore to ESXi 6.5 build xxxxxy - this is not supported.

It's not supported, you can restore state files manually, but you run the risk, if there are code changes between ESXi builds, you can have unpredictable results.

The best thing is to document the build you have, and also make sure you have the patches, iso to install and then restore.
