How can I import an instrument track from one project to another? 

I have a project got messed up, let's call it "OLD" and I want to redo it in to a new project NEW. 

I want to copy tracks from OLD into NEW. The OLD tracks I want to copy have Drum kit from hell (a software instrument). 

How do I copy them? 

I tried: Logic > Import > MIDI. But I did not see the file I want there.

iMac
 Logic Pro X 10.4.8
 EZ Drummer 2 + DKFH (all updated)
