[support] Updating live from dev

[techlists at phpcoderusa.com]

Hi,

I seem to recall hearing there was a way to push changes from a dev site 
to a live / production website.  I know some use GIT and that seems 
good, however I'm wondering about content as well.  Say someone writes 
an article on the test site and when ready pushes it to the live site.  
Or should I only be doing Drupal config / building on the dev site and 
do all my articles on the live site with a backup.  What is the "Drupal 
way" protocol and what will make my life the easiest?

Thank you for your continued guidance!!
