It would be fairly easy to do this to go from the regular vSCSI adapter to the paravirtualized adapter. You'd just need to add a new vmdk to the server using the paravirtualized adapter, let windows detect the new adapter, install the driver, and intialize the disk. Then you reboot the server using a BartPE image that has ghost and the correct F6 SCSI drivers in it and do a partition to partition copy from the old standad SCSI adapter vmdk to the new paravirtualized SCSI adapter vmdk. In my experience this migration takes less time than using VMware Converter.<br><br>Just because we now live in a virtual world doesn't mean all the old physical tools have become meaningless.

Just because we now live in a virtual world doesn't mean all the old physical tools have become meaningless.

You just need to tell the VM to load the drivers first. Check ou the links at the bottom of this article for Windows and Linux. You can boot off PVSCSI.
