cisco wlan controller upgrade

I have at some locations cisco ap 1142. Using this link:https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html

I see that cisco 1140 series is not listed under software version 8.4.100.0 or above. Do we have to replace these access points with newer ones? We cannot upgrade the software for the controller to 8.4.100.0 or above until we replace the access points? Please advise.
