 * I understand from another thread that 3.1 will no longer call the activation 
   hook when a plugin is upgraded.
 * was wondering if someone could point me to a good example of calling upgrade 
   code outside of the activation, so it is called the minimal number of times.
 * My plugin has an internal version number I can use to check against, I’m just
   not sure of the best place to put the check against the version number and the
   call to the upgrade function

 * I ended up putting the check in the admin_init hook.
 *     ```
       function rootsPersonaUpgrade() {
         $currentVersion = get_option('rootsPersonaVersion');
         if(!isset($currentVersion) || empty($currentVersion)
       	|| $this->rootsPersonaVersion != $currentVersion) {
       	$installer = new rootsPersonaInstaller();
       	$installer->rootsPersonaUpgrade(ABSPATH . $this->plugin_dir,
       					$this->rootsPersonaVersion);
         }
       }
       ```
   
 * then
 * `add_action( 'admin_init', array($rootsPersonaplugin, 'rootsPersonaUpgrade' ));`
