I've searched this topic and have read some dated and closed threads pointing to http://codex.wordpress.org/Changing_The_Site_URL, http://codex.wordpress.org/Moving_WordPress, etc. and am more unsure now than when I began this morning what is the best route to take with features currently available in 3.5.1, particularly after having screwed things up and then fixed the test site back to before hacking.
I set the WP sand box site up nearly a year ago for a friend and she has done some content development that probably could be utilized, though we never set out with the intent of recycling content into her new site. Now she says she's ready to try working on the "real" website and before meeting with her tomorrow morning, I'm hoping that some kind soul will share a little guidance for me to give her.
Thank you for any response.
