Update

From Wikipedia

To make an update: Make a backup of the data base and config.inc.php.

- If you have changed scripts, you have to save them separately.

... Ok, have you got already your backup? goood ;-)further:

Delete all files in the PHProjekt directory except:

• config.inc.php
• /attach
• upload directory (in most case named as 'upload').
  
  

Now you can copy the new scripts in the directory and call setup.php with the option ‚update to new version‘. As config.inc.php exists, the script asks you for an authentication. After that the script updates automatically: Some tables will be enhanced and config.inc.php renewed.
