mac upgrade to Big Sur

I am currently using a 27 inch, late 2013 mac. I am running Catalina 10.15.7. As I load different applications, some won't run because I'm not on Big Sur. When I use the System Preferences Software Update I am not given an option to upgrade to Big Sur.


I see it's available in the app store - if I download from there, will the upgrade be properly accomplished?


Thanks -

iMac 27″, 10.15
