When you’re ready to upgrade to Leopard (OS X 10.5), you will need to decide what type of installation to perform. OS X 10.5 offers three types of installation: Upgrade, Archive and Install, and Erase and Install.

The Archive and Install method takes the middle ground. The installer moves your existing OS to a folder, and then creates a clean installation of OS X 10.5 Leopard. This method also offers the option to copy the existing user data, including any user accounts, Home directories, and all user data to the fresh install. Lastly, all network settings used in the previous OS will be copied over to the new installation of OS X 10.5 Leopard. The end result is a clean system installation that retains your user data. Additionally, you get a folder that contains all of your old system data, including your applications and their preferences files, which you can copy over to the new installation, if needed.

It’s important to understand what doesn’t get copied over. Applications, preferences files, and any changes or additions made to system files or folders are all left behind in the previous system folder.
