The Duplicator extension provides a special page which allows the creation of independent copies (with separate edit histories) of pages.


  • Download and place the file(s) in a directory called Duplicator in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    wfLoadExtension( 'Duplicator' );
  • Configure as required.
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


Pages with a large number of revisions cannot be copied if the set limit (default is 250) is exceeded to avoid excessive write load.


To duplicate an article, go to the "Special:Duplicator" page. On article pages (and for monobook skin only) a convenient link is provided in the toolbox which will pre-populate the source page title when used.

Enter the title of the article to be copied and the destination title in the appropriate fields, and select whether or not to duplicate the associated discussion page. The latter option will not be presented if the discussion page does not exist.

Click the Duplicate button to perform the operation. You will be advised when this is complete, or in the case of errors. The copy will be logged in the destination page history, and an entry will be created in the recent changes list.

Note Note: It is not possible to duplicate a page which has more revisions than the configured limit (see above). It is also not possible to overwrite an existing page.
