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.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
