Hi Jasen,
Have a look into VMware Converter... free, fast, easy.
http://vmware.com/products/converter/
We've done production servers with out users ever noticing a difference. I guess it depends on your environment, but we use an ESX server.
If this is the case of moving VMDK's around, you should be able to just restore the vmdk to the server and should see that file.
Hope this helps
---cheers
