Use Existing Page Tree
When you create a Scroll Document, you can transform existing Confluence pages into a versioned document. This places your pages into a Working version where you can make ongoing edits and updates.
To create a Scroll Document from your existing pages:
Find the top page: Search for the single page or parent page you want to become the top page of your new Scroll Document.
Check the preview: Make sure you've selected the right page and that all the pages you want in your document are listed below it.
Enable Scroll Document: Click Enable Scroll Document to create your document.
