Hopefully if you have not hacked any core files all you need to do is drop in all the files within the system folder.

Obviously if you appliction folder is within the system folder dont overwrite it.

Remember backup first !!

Good Luck

Like OES said, as long as you haven't modified core files(highly unlikely) simply drop the new installation onto your current one except for everything under application.

Everything should work because even deprecated things are accessible for backward compatibility.

The user guide has instructions on how to upgrade from version to version.
