I have created a feature, a publishing site, in Visual Studio to MOSS - this feature contains a masterpage, some pages, some site columns (grouped to match each page) etc. I have also created a site collection, some sites and pages based on my template.
Now I need to update some of my page templates and make the changes affect the existing pages - if I change the HTML of the template and updates my feature the changes immediately gets visible on the pages. But if I add a new site column to my page template this does not show in new nor existing pages - but it does in new site collections and sites.
What can I do to get my existing pages updated with the new site columns?
