Import vmdk file from VMWare Player to vSphere possible ?

Hi Community

Is it possible to import vmdk file from VMWare Player to vSphere. I tried already to by import on datastore and create a new VM and with the VM Converter.

- create a new VM with vmdk file in vSphere throws a compatibility error.

- VM converter runs in first try to 22%, in second to 64%.

Is there another possibility to get vmdk file running in vSphere ?
