I am upgrading a 2504 WLC from 8.3.132.0 to 8.3.141.0. I am following the directions that are listed here: https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn83mr4.html
Step 4 mentions this:
| Step 4 |
(Optional) Disable the Cisco WLC 802.11a/n and 802.11b/g/n networks.
| Note |
For busy networks, Cisco WLCs on high utilization, and small Cisco WLC platforms, we recommend that you disable the 802.11a/n and 802.11b/g/n networks as a precautionary measure.

Is it suggesting turning off the radios for the duration of the install, or shutting down the networks in the menus at "Wireless -> 802.11a/n/ac -> 802.11a Network Status" in the GUI? What is this precautionary measure preventing?
