I tried to access support site for 6.5 CE Version but was not able to open that page. It is showing - "This version is no longer supported by SugarCRM". If anyone has CE 6.5 support site backup, then please share.
You can access the documentation for unsupported versions of Sugar at http://support.sugarcrm.com/Documentation/Unsupported_Versions/. You should also review Sugar Community Edition open source project ends, which contains additional details about the CE end-of-life.
