Updating to 1.8.5 from 1.2.1.1? Settings kept?

Hello! Thank you for the Catch Evolution theme. My question: If I update from version 1.2.1.1 to version 1.8.5, will I lose any of the settings (quite a few) that I've specified in the folllowing options: under "Appearance" in WP-Admin: "Customize", "Theme Options," "Header," "Background"? (I did add a scrap of code to "Custom CSS" (for ending the annoying hyphenation) under the "Theme Options".) I'd like to take advantage of whatever is gained from updating the theme but don't want to lose all my settings. I look forward to hearing from you and thank you.
