Redirect from edit page and prepopulate form
You can try using Node Clone module...

Project page says


  The module provides two mechanisms to clone current content. The
  default pre-populates the form for adding a new node, but nothing is
  saved to the DB until that form is submitted. With the alternative
  save/edit method, a copy of the current node is saved to the DB, and
  then presented in the edit form. When using the save/edit mode, the
  admin can set whether a confirmation screen is required, and in all
  cases you can set whether to reset the publishing options on a
  per-content-type basis.
