Upgrade without losing settings

I'm working my way to upgrading to the latest version from 1.8.

According to your directions I'm to "Remove all files from the previous version..." before I upload version 1.9.

How can I avoid losing all my custom configurations like themes, backgrounds and other settings?

Thank you.
