By "redirect" do you mean 3rd party NDMP? That won't do it as it does not manipulate the data steam.
CV would need to read the data stream from the Exadata backup, unravel the ufsdump (or whatever means the Exadata is wrapping up the data) then translate that back into the NetApp version of dump so that the NetApp can read it.
I don't think it does that. Please correct me if I am wrong about this.
