Is it possible to clone PDI?

[Kalyani34]

Hi All, I just want to know that is it possible to clone one PDI with another PDI. I tried to set the "glide.db.clone.allow_clone_target" property to true, but it is not allowing me to do that. It is showing

"This item is read-only based on its protection policy."

I could set this parameter to "true" by script. 

var v_gr = new GlideRecord('sys_properties');

v_gr.addQuery('name=glide.db.clone.allow_clone_target');

v_gr.query();

while(v_gr.next())

{gs.info(v_gr.name);

 v_gr.value=true;

 v_gr.update();

}

But when I try to configure the target.
