You can copy a document as a new document, discussion, or blog post.
Restriction: You must be able to edit the document you want to copy.
To copy a content item:
Go to a document you can edit.
Click Actions > Create a Copy to open the Create a Copy dialog box.
Select the content type for the copied item from the available types.
The available options may differ if the place where the original document is
stored does not support some of them, or you don't have permission to publish a
particular content type there.
Click Create a Copy to create a copy of the
document.
Edit the new item. Note that the title, body, and tags have all been
pulled in from the original document. You can edit all of these, as well as change
the place for the content before publishing.
When you're finished editing, click Publish.
The new item is created based on the source item.
If you want to create a template from a document, see Creating templates.
