Carolyn –
I’m in complete agreement with TMac here, however to simplify matters on your end I would suggest finding/reaching out to a vendor that can stage and rent you some swing gear (controllers/storage) as this would save you both time and aggravation as well as eliminating the need for at least two outage/maintenance windows during your transition from 7-Mode -> CDOT. Just a thought, mind you, but in this instance I think the cost to have swing gear prepared in advance for you and the price of a short term rental would end up saving you both time and money on the operational end of things.

Here are my thoughts on the procedure.
As you should know, ONTAP has a minimum requirement for BIOS and SP firmware images.
You may wish to work with support to figure how far back you can jump.
Referring to
https://mysupport.netapp.com/NOW/download/tools/serviceimage/support/ and
https://mysupport.netapp.com/NOW/download/tools/serviceimage/support/ServiceProcessorSupportMatrix.shtml The FAS8060 can run BIOS 9.6 from ONTAP 9.0-9.5
The FAS8060 can run BIOS 9.4 from ONTAP 8.2.1 - 9.0
Service-Processor firmware:
the FAS8060 can use SP frimware 3.8 / 3.7P1 from ONTAP 9.3 - 9.5
the FAS8060 can use SP frimware 3.4P2 on ONTAP 9.2 releases
the FAS8060 can use SP frimware 3.3P5 on ONTAP 9.1 releases
To upgrade/downgrade the SP firmware, as far as I know, you need to at least "install" ONTAP and configure the SP.
(give it an IP address)
From there, step backwards a little at a time (unless support gives the green light for major backwards jumps)
I was thinking about procedures, I'd prefer not to post without testing. I do not have any gear to test on either.
High level things:
1. you will need to remove ADP. Doing it in ONTAP 9.2 and higher is easy with the new option 9.
2. You must have whole disks, 7-mode has no concept.
3. The SP firmware should be updated to the version that came with ONTAP. It should auto-downgrade for you
4. You will need to install Appropriate BIOS images They are not auto from what I see.
Hopefully this helps at least a little. It can be done, but be sure, it will be a little painful!

What is the system? Is it capable of running 7-mode?

1) we have an 800TB 7mode system
2) we have a new OnTap 9 that has a 7mtt replica
3) the 7mode system is being dismantled and physically moved by truck about 6 hours away.
4) we would like a 7mode snapmirror on a third system that is not being moved
5) we want to use 7mtt cutover tool after the move (based on the customers availability) and not do it manually in the middle of the move.
We need to downgrade a 9.5 system to 7mode. Can you help with that?
Thanks,
Carolyn

The point of 7mtt is to mirror to ONTAP and then cut-over. Yes, it is one way but we have customers doing it quite frequently.
It is not a move, it is a SnapMirror (Transition Data Protection or TDP Mirror).
As along as the mirror portions finish, cutting over is pretty straight forward.
If something unforeseen happens and a manual cut-over has to happen, so be it. It should not be too difficult.

Source is already 7mtt’d but shipping a 7 mode system and need a copy we can run from.
Concerned that if the 7mode system does not make the move well we would have to manually finish 7mtt.

Um... Use 7-mode transition tool from the support site
It allows one way TDP mirrors from 7-mode to any ONTAP release up to 9.5
It will not work with 9.6
No need to downgrade. Honestly to do that is a ton of work and not all platforms can go back that far anyway.
Your NetApp sales team really should have informed you about 7MTT.

Hello,
We are the middle of move planning and need to snapmirror some 7 Mode data.
The gear we have for the destination is from the factory with 9.5.
The usual netboot is throwing errors.
Any suggestions?
Thanks,
Carolyn
