How to move settings/customization to child theme

I made a rookie mistake four months ago when I designed four web sites with Catch Adaptive Pro and made heavy use of the customization and custom CSS menus. The mistake was, I didn't set up a child theme day one. Now, I need one. I've set one up on my test platform, but my problem is that none of my custom settings transfer automatically to the child. Is there a way to do that?
