    Upgrading Cisco Switch Firmware Slow

    I recently upgraded a Cisco 3560X switch. I upgraded from 12.2(53)SE2 to 15.0(2)SE8. I thought this would take 5 minutes max. After ten minutes I was worried.

This happens when updating to a higher version with newer microcode. PHEW! It was a heart stopping 40 minutes.
