Upgrading 3900 Switch

Hi there,

I have a very very old 3900 switch with firmware ver 4.2.0b which I need to get to the highest possible version. (I believe 5.3x). I understand that I cannot re-install so through research I found out that I will need to follow thi path


4.4.0 (any revision



Is the above accurate?

The prob is I cannot find anything below FOS 5.0x. Any assistance would be appreciated
