if you do not have any MODs installed, then there is no reason to update from one version to the next like that.
( if you do have MODs installed then yes, update one version at a time.
with no MODs installed;
1. download the current latest version ( 3.0.4 for now )
2. unzip it to your computer
3. take the blank config.php file out of it
4. upload all the rest of the files and folders to your server letting
them overwrite the ones that are there.
5. in your browser, go to:
yourdomain.com/yourphpbb/install/database_update.php
6. delete the install folder
7. you are done.
