Vmware Converter does work for almost anything, what you would need to do is cold clone the server…
make sure the hardware is on ESX’s compatibility list…. this is a free download… <a href=”http://www.vmware.com/download/converter/”>http://www.vmware.com/download/converter/</a>
Read page 45 and on on cold cloning requirements from this <a href=”http://www.vmware.com/pdf/VMware_Converter_manual303.pdf”>pdf</a>
One more thing… I suggest, shutting the server down and installing an INTEL Gigabit Ethernet adapter, connecting it to a gig network then, booting with the cold clone cd… it would take hours with a 10/100 ethernet adapter.
Hope this helps!
