Each Knowledge Base is essentially a separate knowledge base designed for different sites to embed. When managing large amounts of content, being able to move content between Guides helps with organization. You can move collections along with their categories and articles between different Guides.
To move a collection:
Navigate to the control panel and select the Knowledge Base you want to move content from.
While viewing your collections, click the edit button for the collection you want to move to access its settings.
Choose the new Knowledge Base you want to move the content to.
Click the save button.
The content under the selected collection will now belong to the new Knowledge Base. Note that content in the embedded widget on your site is cached briefly for an optimal customer experience, so there may be a slight delay before changes are visible to your website visitors.
