How to upgrade from 4.5.2.3 to 4.5.3 beta

I don`t know hot to upgrade!! Any ideas?

Do not upgrade your production site for the moment. Just install Mambo 453 as new, for test purposes on your local server.

Just FTP all the folders except \installation

and for the files FTP but DO NOT change your old configuration.php file at your server.

I forgot. You do not have to delete any other file or folder.

Hope this helps.

Sorry, I forgot do not FTP the INSTALL.PHP from the 4.5.3 root directory.
