Best Way To Deploy Yii Developed App

Can you please share your experience of the best way to deploy a Yii developed application?

I have not been able to find any good documentation of how to package a Yii developed app, give it a version number and move it to a production environment.

For example, I recently deployed my application by first deleting all files/folders in the root directory and then replaced them with the new files/folders. Is this really the way to go about, or can you please guide me in the right direction?
