Each Guide is essentially a different knowledge base meant or different sites to embed. When managing larges amounts of content and getting organized being able to move the content between Guides becomes helpful. You can move collections and their children categories and articles between different Guides.
In order to move a collection, first navigate to the control panel and choose the Guide you want to move content from.
Next while viewing your collections, click on the edit button to display the collection settings.
Next, choose the new Guide you want to move the content to and click the save button.
You're content under the collection you've chosen now belongs to the new Guide. Content in the embedded widget on your site is cached for a short period for optimal customer experiences. There may be some delay for the changes to be live to your website visitors.
