Using DELL R630 server, planning to downgrade the NIC firmware version

Hi Experts,

is it possible to do the downgrade of firmware version?


I have tried with using .BIN file also using IDRAC from DELL server approach.

As i have tried do the downgrade of firmware version from 24.x to 23.x , 22.x, 19.x and 18.x but its not doing the downgrade and give below error message:



dmesg -T | grep -i i40e

Or Please let me know the what are the possible ways to do so.

@PaulWilli Thank you for the quick support.
Do we get any specific link to gather information w.r.t upgrade and downgrade process and scenario

Thank you
