    Does anybody know whether you can move a VMware RDM from an existing VMware VM by first powering it off and removing the mapping and then present the same to a Hyper-V R2 cluster and attach it to a Hyper-V R2 VM.  For example, in this scenario, we would use SCVMM 2008 with SP1 to V2V the VMware VM to Hyper-V R2 but of course won't be converting the RDM (that contains a lot of data) to a VHD.  We would then want the RDM to be presented to the Hyper-V R2 Cluster and then added to the converted VM as a pas through disk.  Would this work or would the partition be unique to the original VMware VM?

    Any other advice appreciated.

    Hi!

    Although I haven't actually tried this myself, I think you should be able to do this. Passing through disks in either VMWare or Hyper-V would still make it possible to put the disk online and access its contents on a physical machine.

    Neither VMWare or Hyper-V adds any hypervisor information on a passed through disk, that I'm aware of.

    I see, thanks.  Will give it a go on a non-production RDM and see what the results are.

    did you give it try migrating VMs with RDMs (Windows Failover Cluster) from VMware to Hyper-V cluster? 

    If yes, please provide some information on this on basis of your experience..

    RDM is VMware's disk format.  Hyper-V does not recognize it.  You need to convert a VMware RDM formatted disk to an NTFS or REFS formatted disk (physical or virtual) for Hyper-V to recognize it.
