I had upgraded IOS image on cisco 2960 Switch. Previously it has version 12.2(44)SE5 image. I upgraded to version 12.2(53)SE2 image.My IOS is upgraded sucessfully and working fine. Recently i noticed that boot loader image was not upgraded. It shows the previous image in boot loader.My question is why boot loader image was not upgraded along with ios image upgradation?please suggest.
The boot loader does not get upgraded every time you upgrade the IOS. It all depends on how old IOS version you had. So in your case 12.2(44) was not a very old IOS version, and when you upgrade to 12.2(53), the boot loader does not necessarily need to be upgraded along with the IOS.
