Duplicate paragraphs from node type FOO to node type BAR

Question

I have two content types: FOO and BAR. These content types have a field called "field_paragraphs" of type "paragraph". And other fields of course.

Now in a situation my user can click a button (that call one of my function defined via hook_menu) and "copy" content of type FOO to a new content of type BAR, so I need to copy, NOT CLONE, field_paragraphs from FOO to BAR: I need to create a standalone copy of "field_paragraphs"; like two different insert.

I have searched on google but all talk about "clone", but in my case I need to copy so I can not use "clone" module.

How can I do this ?

EDIT: You can now find a better explanation with the code here.

I know this is old but maybe someone comes here looking for an answer like me, this is tested on Drupal 8.

I found this issue and after looking at last patch, I implemented :

$nodeDuplicate = $node->createDuplicate();

foreach($nodeDuplicate->field_paragraphs as $field){
    $field->entity = $field->entity->createDuplicate();
}

$nodeDuplicate->save();

And I got a duplicate node with duplicated paragraphs fields. If you look at the patch you will see how to add a button to Drupal etc.

Just a note field_paragraphs is the name of my field in the content type, change it with your own.

I didn't have any problem doing it this way, maybe someone has a better way but I did not find it, also at the time of writing this there is still no ported modules for cloning nodes in Drupal 8.

This is an example that could give you an idea how to do it.

   function copy_node_foo($node) {
      if ($node -> type == "FOO") {
          $node_bar = new stdClass();  // Create a new node object
          $node_bar->type = 'BAR';  // Content type
          $node_bar->language = LANGUAGE_NONE;  
          node_object_prepare($node_bar);  //Set some default values
          $node_bar->title = 'Your node title';
          node_bar->field_paragraphs = node->field_paragraphs;
          /* others properties .... */
          node_save(node_bar);
      }
    }
