Your not the only one confused here but let see if we can fix it.

I belive do this with a testsite first would complicate it too much. Personal I would test install 3.0.3 on the friends host but only after I taken full backups on all files/folders and databases through the hosts control panel and also by copy all the files/folders with a FTP proggie. In a case things went bad you could rather fast get your friends orginal site back and working again. IPB recommends when you do the upgrade that the site is set to offline mode.

The things you today have installed on your board you had to reinstall.
