im trying to downgrade a new FAS8040 wich cames with version 9.1P2 to a 8.3P2 version, but i've been only able to downgrade to version 8.3.2, whenever i try to boot from 8.3P2 i'm on a bootloop. From the HWU i understand that this is posible, but for sure that im missing something.
This is a new cluster so i did it through options 7 and 4 of the menu, install software first and zeroing/cleaning config.
i can attach something, i have the 83P2 on the backup image of the system, this is the output of the system console:

Hi I have just ( 2 weeks ago) went through a similar situation with the support of NetApp. There is a few things that you first have to do however - This was the procedure we followed: Upload the software images to the http server downgrade the SP to a version supported by this version of DOT (we used this version: 03744_A0_FAS80X0_3.0.3P2_SP_FW.tar.gz -- SP firmware 3.0.3P2). We then changed to 7-mode, and went into 7 and 4. There is a few firmware upgrades / downgrades which it goes through, but eventually you will get there. Do not break the nvram upgrade / downgrade as t5hat will cause a boot loop stop, and you have to start over... hope this helps - my feeling is that the problem might be that you have not downgraded the SP.
thank you for all the answers, some clarifications:
Just now, i've just downgraded to 8.3.2P11 without issues, but i was just wondering what was impeding me when trying to downgrade to 8.3P2, as this is the realease that most of our filers are on, so that's the main reaseon for trying to reach this version.
I think that i will stay on 8.3.2P11 as as you said, this is the recomended release of this branch from Netapp.
