MD3600F - How to replace redundant RAID controller with another containing a newer version FW

Hi All,

as per the subject, I have to replace one of the two RAID controllers on a MD3600F FW version 07.84.53.60 with another spare that I have had in stock for a few years and of which I do not know the installed firmware version. I know that in the case of installing a ctrl with an older version, the active ctrl automatically aligns the fw of the ctrl just inserted to its version, I have no idea how the system behaves by adding a ctrl with a newer version such as 08.20.24.60. I would like to prevent the system from overwriting the currently working FW to avoid compatibility problems with the connected servers.
Is it possible to disable the automatic firmware update?
I thank in advance those who want to help me.
Regards
