This plugin has been developed by Yudiz Solutions Ltd. It will help you to replicate pages, posts as well as custom posts.
How to use this plugin?
1) In edit posts/pages, you can click on ‘Replicate’ link which will create a replica of that particular post/page and return back to the list.
2) This plugin also retains the state of the original post/page. To exemplify, if we create replica of post/page, it will be in the draft state with ‘Replica’ name.
3) If you need to edit the replica then it can be done in the same manner as you do with regular post/page.
4) In order to replicate in bulk, you need to select all those posts/pages and then afterward choose ‘Replicate’ option from the ‘Bulk Actions’ dropdown that appears on the top of the list.
