Hi, does anyone has any idea to go about upgrading the ios for a 3750 switch stack using binary file? Cisco website has only instructions for using tar file to upgrade. I have tried the conventional way of copy the new bin file into both flash1 and flash2 and changing the boot config to boot with the new image. But when I rebooted the stack, only the master switch is upgraded and the 2nd was not able to join the stack as the master detected a version-mismatch. Reason for using bin file instead of tar file is because I do not need the CMS in our environment. Any advice will be greatly appreciated. Cheers.
