Standard procedure to upgrade ;

Note: read the release notes, check the compatibility with AP, version of upgrade you looking to go.

Check https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html to ensure WLC/ APs are compatible with planned software version
- Also check things like Prime/ DNAC/ ISE versions are compatible with the WLC version
Check you are planning TAC recommended software version: https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html
Dependant on the current software version version and AP models on you may want to run the WLAN Poller https://developer.cisco.com/docs/wireless-troubleshooting-tools/#!wlan-poller-wlan-poller/wlan-poller to ensure that you don't have any APs with flash issues (which will cause them to fail upgrade and get stuck until you manually console them to recover them)
Plan a wireless outage window
Use the pre-download software to APs
Implement outage window which will reload the APs and WLC and they will all upgrade and re-join the WLC
Check everything is working
