Hi Ayub,
If you are looking forward to promote the content from between BI 4.x you have to use LCM_CLI Tool to do it.
I have created a forum which will definitely help you to achieve the target .
Please check : How to promote all content from SAP BI 4.x to SAP BI 4.x using LCM_CLI.bat (Command Line Tool) using Live to Live method.
Hope this will help.
