FUS upgrade to release 2.0.0.0

[lilanthadilan]

As per cisco release notes on FUS version 2.0.0.0

the bootloader version is 1.0.20 only if FUS version 2.0.0.0 is installed.

I have a cisco 2504 controller which has bootloader version 1.0.20. Could we conclude that its installed FUS version is 2.0.0.0?

Manufacturer's Name.............................. Cisco Systems Inc.
Product Name..................................... Cisco Controller
Product Version.................................. 8.2.166.0
Bootloader Version............................... 1.0.20
Field Recovery Image Version..................... 1.0.0
Firmware Version................................. PIC 16.0

No. 

As per my knowledge PIC must be 20.0 if you would have upgraded to FUS 2.0.

Sandeep - however the release note https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/fus-rn-20.html says "Cisco WLCs with PIC version older than 1.0.18 will not show PIC update when upgraded to FUS 2.0" even though https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuu46671 says "This bug is fixed in Firmware version PIC 20, which is included in the FUS 2.0 release." So it might be that PIC is only upgraded if running 18 or 19?

There are multiple pieces to the FUS upgrade and if you run the FUS upgrade, it will prompt you with the current and the new. If the current and the new is the same, you can skip the upgrade of that one part. If they differ, you can hit yes to upgrade.
If you don’t have any issues with your device, don’t worry about it, but if you feel like part of the FUS has not been upgraded, run the upgrade again, but make sure you are on the console and watching.
