Updating a cisco 4431

I am not sure exactly where to submit this, but i have been assigned (at work, where i would like to impress my coworkers) the task of updating a cisco 4431 from Fuji 16.8.1 TO denali 16.3.7.

i thought this was going to be straight forward, but i quickly learned the contrary.

First of all, on the current iOS, their are hundreds of tracelog files that come back after every reboot even when deleted (is this normal behavior for a router?)

Secondly, also located on the bootflash: are a series of firmware files.

I am wondering how i can correctly and successfully upgrade to this new iOS and what i need to do about the firmware files.

Any and all help is appreciated and i apologize if this is in the incorrect section.

Are you still having issues with this? I ran into similar issues trying to upgrade a 3850 switch. Upgrading the IOS is a bit different than copying a BIN file to the flash.

In my case, I had to use the software install command to force an upgrade. Are you getting any errors when installing the newer version? It’s normal to see PKG files on your flash btw, those get installed:

I don’t see the tracelog files here. What do they contain?
