The alternate versions workflow starts with a published post.

WordPress uses the term post generically to refer to all content that shares the Post admin user interfaces. A post type is a specific instance of a post — both Post and Page are built-in examples of post types. In addition, plugins and themes may add their own custom post types for managing special types of content. For instance the BU Profiles plugin uses a custom post type called Profile to allow management of faculty and staff profiles.

The alternate version workflow is designed to work on published content. Publish is an example of a post status — other statuses include Draft, Pending, and Trash. If you see one of these status labels next to your post title on the edit posts page, you will not be able to create alternate versions for them.

By default all post types that appear in your UI will gain the alternate version workflow.
