    The best option is using converter

    Hi Sudheer,

    Using vmware converter you  can do V2V. But it is lenthy process.

    Using command mode it is very easy to downgrading Hardware version 7 to 4.

    ->poweroff vm

    ->make sure vm dosen't have snapshot

    -> login to esx console from putty

    edit vmx file of vm

    vi /vmfs/volume/datastore/vm folder/ vm.vmx

    datastore-> where vm is located

    vmfolder-> vm file (like win2k3)

    Edit insted of

    "virual hw.version = 7"

    to

    "virual hw.version = 4"

    and

    scsi0.virtualdev ="lsisas01068"

    to

    scsi0.virtualdev = "lsilogic"

    save it.

    Next Edit .vmdk file hardware version using

    vi /vmfs/volume/datastore/vmfolder/ vm.vmdk

    Edit

    ddb.virtualh HW version = "7"

    To

    ddb.virtualh HW version = "4"

    save it, and poweron your vm
