The original Sequel Naturals and My Vega sites were built together as one Drupal 5 site. 313 split them out into separate Drupal 6 sites and installed them in a multisite configuration, using a base theme and sub-themes to keep fundamental design and layout consistent across the sites. Custom scripting was used to separate the content into the proper sites and rewrite the URLs. Many site-specific modules and theme functions were upgraded or rewritten for Drupal 6.
