NDMP restore from ONTAP 9.11.1 to Data ONTAP 8.2.5P5

[Quang-Chinh]

Customer is asking the following : 

Is this possible to restore a data that has been saved with ONTAP 9.11.1P11 via NDMP to a FAS2552 running 8.2.5P5?

Could you help us to confirm this to customer?

theoretically it may work

according to old papers

"Clustered Data ONTAP volume can be restored to a 7-Mode volume"

but it may depend on too many variables , like how the backup was made

if it was smtape engine f.ex. then I'd expect it won't work
