====== Switch IOS Image Upgrade ======

**General Information**

This method uses a better way than TFTP to move images to the target device.

**Checklist**
  * SSH/SCP agent installed. (Putty or other OS package)

----

===== Send the Image =====

1) Enable SCP on target device.
<code>
ip scp server enable
</code>

2) From PC, scp image to switch.

On Windows, with putty's pscp:
<code>
pscp -scp C:\new-image.bin username@switchname:new-image.bin
</code>

3) On the switch, set new IOS as primary boot, old as secondary.
<code>
conf t
boot system flash:/new-image.bin;flash:/old-image.bin
</code>

4) Save config, reload
<code>
copy run start
reload
</code>

5) Once verified that switch boots to new ios and no bugs occur, feel free to delete the old image.
<code>
sh version
delete flash:/old-image.bin
</code>
