VM is sysprepped but even then error 10659: template doesn't have generalized VHD

Hi,

We patch a VM then sysprep it and create VHDX using Export-VM command. This VHDX is used to create a VM Template on SCVMM. After we create a template successfully when trying to create a VM from this Template we get error; 10659 Cannot run Sysprep on virtual machine <servername> because the template does not have a virtual hard disk attached that has been generalized.

Help needed...

Thanks, Kishor
