I need firmware version 2.9.1000 but the cards have 2.9.1050

Do I need to downgrade the cards from 2.9.1050 to 2.9.1000 for CentOS 6.6?

Thanks in advance. I have > 80 cards so not having to flash these would help immensely.

I wouldn’t recommend, these versions have nothing major that justifies downgrading.

Out of curiosity, which model cards are you using?
