During one of my presentations the other day I had mentioned a tool that can migrate physical and VMWare machines to virtual machines for Virtual Server and HyperV (once SCVMM supports HyperV).  An attendee had emailed me to get more details, so here are the links to the information on System Center Virtual Machine Manager (SCVMM) Converting Physical Computers to Virtual Machines in VMM (P2V Conversions)  and Converting VMware Virtual Machines in VMM (V2V Conversions) .
