Redirect from edit page and prepopulate form I would like to redirect user from node edit page to node add page but with prepopulated form. So all fields of the form would be pre-filled with copies of values of node edited before. Is there a way how to get these values and fill them in the 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.
