Take a backup of your database and note down your current version of PawBill. Also save a copy of app/config.php from your PawBill directory.

Download the latest PawBill package from the download page and then delete all the PawBill files from your server. Extract the downloaded package and upload it to the correct location on your server. Be sure to use binary mode while transferring the files using FTP.

To start the upgrade process, you can navigate to the admin area url of your PawBill installation. This will automatically redirect you to the upgrade page. For example, if your PawBill installation URL is http://billing.yourdomain.com/, visiting http://billing.yourdomain.com/admin/index.php will redirect you to http://billing.yourdomain.com/install/upgrade/index.php which will start the upgrade process.

At this point, your files are upgraded to the latest version while your database is still at the old version. The rest of the upgrade process will bring the database up to the same version as the files.
