Re: Need to quickly downgrade from 9.5 to 8.2.4

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!
