Folks,
We have a rebranded NetApp array (IBM N-series) that we upgrade the ONTAP from 8.1 to 8.2 a few months back. In upgrading to 8.2, the protocol licensing keys were upgraded to the long format and also bound to the controller's S/N. Recently we had to replace the motherboard and now we've lost licensing on the one controller. The partner node is still licensed, both nodes are running.
I am thinking about doing a "cf takeover" from the partner node and trying to downgrade the ONTAP back to 8.1 version on the controller with the replaced motherboard. Then reapplying our original 8.1 license keys and then upgrading back to ONTAP 8.2 version, while leaving workloads running on the partner node.
Has anyone tried anything similar in the past? Any potential gotchas you can share?
Thanks, Eric
