There are two most used methods to update to the newer versions, the first one is using System Update or known OTA. This method is the most less effort a user can use, however it takes a strong and stable internet connection as you will download the entire firmware files.
And the second method, we can use manual installations. This method requires you to have Odin, a computer based on Windows, a USB cable and also enabling your device USB debugging mode.
If you have all the requirements then you are good to go.
