Would be any problem if just upgrade the software and not the FUS?

FUS contain some patches that otherwise are not covered by the standard software.  Recommendable if you do upgrade the FUS. 

Be warned that the entire FUS takes about 35 to 40 minutes.

"Field Upgrade Software (FUS) is a special AES package that contains several system related component upgrades. These include the bootloader, field recovery image, and FPGA/MCU firmware. Installing the FUS image requires special attention because it installs some critical firmware. The FUS image is independent of the runtime image"

Yes, this is highly recomended to do this upgrade. Otherwise you may have wired issues of APs are not working as expected.

Here is a document explain this process

It doesn't matter as long as you get it done. 

Make sure you reboot the WLC before doing the next.

Hello Rasika,

Hello Rasika,

Kindly let me know which one should be upgrade 1st FUS or the Software Version. 

Or it will get done once we upload both image on WLC.

Rushikesh,

Rushikesh,

The FUS and controller images are separate and done in either order. Each requires you to upload the image and then go through the reboot. You can't upload both images and reboot once.  Treat each as a separate process.
