Back up your data, check the application compatibility table, click here, and then on the download link for a newer OS. A Mac on Sierra can be upgraded at least as far as High Sierra; if you encounter a specific issue, describe it in this thread, and if you're trying to go past that, say what the computer's model year is.
Catalina and above won't run 32-bit software and split the functions of iTunes up; if you choose one of them, use Go64 as well.
