VM converter error while moving a virtual machine to another esxi 5.1 server

Hello,

I trying to copy a vm that's on an old amd processor to another system with a newer socket amd processor using the latest vm converter standalone.  I get the following error "Unable to validate the destination.  Error:vmodl.fault.SystemError"  the esxi 5.1 versions are the same on both servers and the difference is the older is regular SATA vs SATA raid controller on the newer system.  Any help will be greatly appreciated.  The VM that im trying to move over is Windows 2008 R2 64 bit.

Thanks
