4900m IOS upgrade from 12.2(54)SG to 15.1(2)SG7

I was not able to find any documentation that referenced upgrading the IOS in steps. I did find documentation that requires the ROMMON to be at 12.2(44r)SG5 which is what I have. So will I run into problems if I upgrade straight from 12 to 15?

Hi,

Can you share the file name of the 12 version that you are currently running along with the 15 version that you want to go to?
