Backing up the current version of firmware to your TFTP using the following –

Upload to your TFTP root, note the name of the firmware example here is R.11.112.swi
Copy the file to your switch
switch# copy tftp flash 10.1.1.10 R_11_25.swi primary
The Primary OS Image will be deleted, continue [y/n]? y
You’ll see a progress counter as the file is transferred, then:
Validating and Writing System Software to FLASH...
After it has completed, we can verify success by examining the contents of flash:
switch# show flash Image Size(Bytes) Date Version ----- ---------- -------- ------- Primary Image : 3790986 24/4/15 R.11.112 Secondary Image : 3689315 01/25/08 R.11.07 Boot Rom Version: R.11.112 Current Boot : Primary
We can now reboot the switch with the new firmware:
switch# reload Device will be rebooted, do you want to continue [y/n]? y
After the switch boots back up, we can verify that it is running the latest firmware:
switch# show version

HINT: Always read the release notes before upgrading firmware, sometimes you cant upgrade direct to the newest version and need to do the firmware in order
