We're looking to upgrade IOS and if I understand the somewhat cryptic version numbers, as we're just looking for bug fixes, 12.2(25)SE* would be preferred.
So looking into what is available, I see: 12.2(25)SEE4(ED), but this is deferred with 12.2(44)SE5 recommended instead.
However, 12.2(44)SE5 is deferred too, so 12.2(44)SE6 seems like the next upgrade for us.
Is my interpretation correct?
Secondary to this, I notice the size has jumped to over 10Mb, which pushes it over the free we have on the flash. Presumably this means I'll need to remove the existing IOS on the flash before loading the next one? Is doing this safe?
Thanks. According to the Cisco Software Download page, the latest release for your switch is indeed the 12.2(53)SE. If you are using a switch stack with your 3750, you will have to upgrade all switches in a stack to the same IOS version.
