Before making any changes, back up your existing configuration. Cisco’s official documentation recommends saving your startup configuration and copying it to an external TFTP server or USB drive. Execute these commands:

Rename the previous image rather than deleting it. One community user documented renaming the old firmware to a .BAK extension before copying the new image, providing a simple rollback mechanism if the upgrade fails.

Cisco digitally signs its release software. The switch automatically verifies the digital signature when you set the boot variable. You can also manually verify with:
