How to clone Universe and Reports

Hi

I have a BO 3.0 installed on MachineA.

Now I created Universe1 and Webi Reports 1,2,3

Universe 1 uses Databse1

Now I want clone same Universe and Reports but point to some other Database like

Universe2, Report11, report22, Report33

Universe2 Points to Databse2

I have do this on same machine (i.e. Same BO installation)

Any pointers?
