So let's try this another way.  I spent a great deal of modifying a theme.  How do I make a copy of it - the modified theme -menus, colors, fonts, custom css, etc.  to the staging site?  In essence, I want to clone the active site and set it up as a staging site.

Sure.  That I know.  What I want to know how to copy is all of the changes I made to the original template.  Colors, image changes (taking out the template ones), custom css, font changes, etc.  SO far I am forced to redo all of that one piece at a time.
