Copying Map Information from One Biztalk project

Biztalk support needed.

My new task is to develop a Biz talk Project. Since m a fresher into this. I have no idea of how to add an existing map.Actually i already have a project which has biztalk file and i can see the mapping via biz talk mapper i want to apply the same mapping in my new project. I already included the schema file.
Is there any way through which i can copy the exiting mapping from the older project to this new one without having to do it manually. Both the projects are in 2009.Please help
