    We are replacing our DPM 2012 R2 server hardware and storage and I have a quick question about “pre-staging the data” by creating a manual replica on the new server.  The protection group members on the old DPM server are de-duplicated volumes from 2012 R2 file servers on our WAN.

    Unfortunately, DPM doesn’t support chaining of deduped protected volumes.  Therefore, moving to the new DPM server is not a simple matter of setting up DPM chaining with the new server and switch protection server. Because of the “chunk store” involvement, it is unlikely that the method described at https://technet.microsoft.com/en-us/library/ff399552.aspx to pre-stage replica data will work.

    So, is there a way to migrate already de-duplicated data from one DPM server to another that doesn’t involve rehydrating the data and then a consistency check which may transfer large amounts of data across our WAN.

    Anyone?

    Transferring all backup data across WAN links does not sound like an acceptable solution....

    Bueller?... Bueller?... Bueller?...

    Seriously, am rapidly approaching the start of this project. If anyone has been in this situation, I really would like to hear from you.

    The prospect of having to transfer this data over the WAN link isn’t appealing.
