Macworld:
"You’re now ready to start up from the Tiger disc and run the Installer. If you are upgrading a drive that is currently running Panther, the Installer’s default selection is Upgrade. This means it modifies or deletes existing Panther files, as needed, installing the Tiger modifications and files as replacements.
However, you have other choices. If you click the Option button in the Installer’s Select a Destination screen, you can select to Archive & Install. With this method, the entire Panther software is moved to a separate folder called Previous Systems; a completely new install of Tiger is put in its place.
I strongly recommend doing an Archive & Install (adding the option to preserve your Home directory and Network settings) rather than an Upgrade. While an Upgrade generally works well, it can lead to problems if, for example, you have modified or moved any OS X files such that the Installer can no longer upgrade them properly."
