We installed 4.5.1 in a subdomain (v4.usused.com) as a testing server so we could customize before going live. What steps need to be taken when moving the code to the main domain?

Assumptions:
  1. backing up main domain files
  2. copying subdomain files to root directory
  3. modifying the "RL_ROOT" definition in the config.inc.php file in the Includes folder
  4. modifying the "RL_URL_HOME" definition in the config.inc.php file in the Includes folder
Are there any other steps I am missing?
