Export Upfront pages for import to another site?

Because of experimenting around with various plugins, pages and features on this site, the database has grown to a sluggish 63MB!

Two tables appear to be the main culprits
- wp_options is 5.4MB
- wp_postmeta is 54.6MB

I'd like to do a fresh WP install but it will waste a day to recreate the site manually and I'm 11 days from launch with heaps to do.

Is it possible to export Upfront created pages for import into another theme or what other advice can you offer?

Much appreciate any suggestions.
