Hi Mjzzini
Thanks for your reply. So, in that scenario, there's not guarantee to migrate the data without lose file permissions integrity.
I saw also about xdp or Robocopy but I don't if they will work from NetApp(7-mode)-to-any and then, any-to-NetApp (ONTAP 9). Please let me know if they could be at least work just to keep the data at least. Thanks!
