Upfront - Export or Migrate customization to new site

What is the recommended process for exporting or migrating upfront customization?
Are they stored as separate database tables that I can just move into a new site?
Can I use wordpress export to export the customization (Is it its own post type or tied to existing pages?)

Upfront is revolutionizing my development process, I look forward to it's continued improvement, It has come a long way since 0.1 release, and is getting more stable.

I send my gratitude and thanks to the teams involved.
