Hi Manish -
You can clone each Entity you need manually. Do a search on the forums for the word "Clone". But you'll need to manually do this cloning on every Entity, for every one of your copy scenarios.
Many of my apps require this copy functionality. Because of this - I have implemented RecursiveCloneAsNew(), which will automatically clone an Entity & all its related Children n-Levels deep, while also maintaining references to its Parents. You can find more information on it within these forums.
Please contact me directly if it's something that would benefit you. Take care!
