Fedora 32 will continue to receive updates until approximately one month after the release of Fedora 34. The maintenance schedule of Fedora releases is documented on the Fedora Project wiki . The fedora Project wiki also contains instructions  on how to upgrade from a previous release of Fedora to a version receiving updates.
