Thanks, Brad and Alexander, for your input. Correct, this is a Production machine so I’m hoping to avoid having to go the factory wipe route. It’s sounding like a downgrade
on ONTAP would work, but probably not worth the amount of effort involved (e.g., reverting RAID labels)?
This machine had been on IBM Support, but now is on 3rd party HWMA contract. I’m pushing them to work with IBM to get new keys reissued, but I wanted to have a
2nd option just in case IBM and/or NetApp pushes back and unnecessarily delay us getting the keys.
Thanks all,
Eric

Sure, on a fresh install it should work, but I'm assuming that this is a production machine that he doesn't want to wipe out (correct me if I'm wrong here).
As far as NetApp providing new keys for the new board, it's not going to happen. I've asked. Basically, unless you are the original purchaser of the motherboard (from NetApp) they will refuse to assist you. Additionally, this is an IBM N-Series so he would
need to go back to IBM support who should be able to assist with the serial number change procedure.

Hey,
downgrading or installing fresh with the keys which you do hopefully have stored somewhere will work, I’ve gone through that also once, but it’s easier to let NetApp convert your keys. I’m not sure if this can only be accomplished with an active service contract, but I think it might be worth a try. If your system was still under maintenace when the target Ontap version was released, you might be lucky.

Betreff: Re: 7-mode DOT downgrade question
When IBM support does a motherboard change they actually change the serial number of the board. Once the serial number of the new board is changed to match the original board the 90 day timer on the license keys will stop.
If you don't have an active contract with IBM, I would contact them to see if you can get some kind of 1 time support contract. Let them know that you had to replace a motherboard and you need the serial number changed.
As far as a downgrade goes I wouldn't do it, but that's just me. The list of things needed to be done to actually complete a downgrade from 8.2 to 8.1 is about as long as your arm. For instance, any snapshots that exist will need to be deleted, among many other things. It's actually a revert that would need to be done, so trying to do a takeover to accomplish this wouldn't work. The RAID labels on the disks have already been upgraded, so a system that is running 8.1 wouldn't even be able to properly recognize the disks that have been upgraded to the RAID label version that 8.2 uses. The labels would have to be "reverted" in order for the system to use them.
Honestly, even if you went through with the revert I kind of doubt that you would be able to reapply the key. Something tells me that NetApp would have thought about users doing that and built in some kind of mechanism to counter it.
IMHO your best bet is contacting IBM and paying for some kind of support that would get them to help you through a serial number change.

Subject: 7-mode DOT downgrade question
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
