If you want two wiki pages to display the same content, consider linking from one page to another, or using an Include page, rather than copying the content from one page to another. For information on using an Include page, refer to Including the Content of a Page on Another Page. Copying may be acceptable when preparing drafts for review before release, or when a new page needs similar content (not the same content) as an existing page.
You can copy a page. For details, refer to:

The copy is saved in the same location in the page hierarchy as the original page. The word 'Copy' is added to the page title.
To make the page useful you must do the following:
- Move the page to the location in the hierarchy where you want it to be.
- Change the page title.
- Ensure all the links from the copied page open the intended targets. For example, if you are copying a family of pages, edit the links so they open pages with the new page titles, rather than the original pages.
