Please Read:  Before starting the Control Center Director upgrade/uninstall process, you must backup the entire "conf" directory found under Control Center Director install location.  Please follow the steps below before upgrading: The following instructions apply to maintenance upgrades.
 
1. Stop Control Center engine
2. Take a snapshot of the IBM Control Center Director database for fall back purposes.
3. Back up the existing configuration data: conf folder of EP and web/conf folder of CCD.
4. Run the installer and select the existing IBM Control Center Director installation folder as the destination folder.
(The installer would automatically un-install the previous version - but all the configuration data will still be there).
5. For all prompts, keep the same value that was defined in the previous version and click Next.
Important: Do not select Yes for reinitialization of the database for either Production or Staging.
