Blog Posts are transitioned into News Story, which will hold all original stories in Atlantis.
Advertorial is a simple flag placed in all across the content type. Any content type can become advertorial and used for sponsorship with the flag on.
Flash (.swf) files will be treated as Videos in Atlantis, and no new .swf files can be created.
Polls are transitioned into Atlantis as Page content type. It needs further exploration on whether they are editorially valuable.
All the services that Webservice supported (e.g. YouTube, Twitter, etc.) would be now supported within the text editor of each content type. Users can easily embed the assets using either the embed code or URL.
Webresources are transitioned into Promos, where Prime Editors can upload an image, internal and/or external link, title, and description.
