See here: How to upgrade to macOS Catalina - Apple Support


Do note that Catalina does not run 32 bit Apps, so any older apps not updated to 64 bit you are currently using on 10.9.5 Mavericks will not work on Catalina.


The Catalina installer will show you a list of incompatible apps before you update so you can verify what will not work.
