Is it possible to move shelves (with entire agregate) from c-dot 8.2 to another system using ontap 9?
Same process that was possible on 7-mode systems.
See The Solution
You will need to do some downgrade/upgrade to be able to do it. And to be supported you need to move the shelves together with the old root volume (Means you can’t merge it with the new 9.0 cluster if you already created it – “Accessing the foreign volumes inside these aggregates on the clustered Data ONTAP system to which the shelves have been migrated is not supported” from https://kb.netapp.com/support/s/article/how-to-remove-or-access-a-foreign-aggregate-an-aggregate-made-out-of-orphaned-disks-in-clustered-data-ontap

The correct term is moving shelves, not head swap.. Because we were able to do that on 7-mode.
