M8024-k CLI scp firmware upload failing

I have 11 M8024-k switches I need to upgrade the firmware on. They're currently on 5.1.7.5 and I need go to 5.1.13.1.

I use the command "copy image scp://username@192.168.1.1/Imagename.stk" and it ask for the password of the scp server. I enter it and it prompts about not being to use management while it's copying. I tell it yes. It then proceeds to copy and says the copy completed after it uploaded so many bytes.

After this I do "sh ver" and it shows that the current image is still 5.1.7.5 and image2 is 5.1.0.1

It never shows that the new code is uploaded and I've tried this on three different switches so far. Any idea what's going on here? This is the same exact way that the firmware upload pdf is showing how to upgrade the firmware.
