if we go by the direct meaning of your question....there is no need for a new mapping for a new databse, you just need to change the connections in the workflow manager to run the mapping on another database

u can also do it this way. connect to both the repositories, open the respective folders. keep the destination repository as active. from the navigator panel just drag and drop the mapping to the work area. it will ask whether to copy the mapping,say YES. its done.
