How to Mass COPY all threads from 1 forum to another! (kind of exact duplicate copy)
 

How to Mass COPY all threads from 1 forum to another?

Lets say I have 500 threads in Forum A , I want to "COPY" these 500 threads to another Forum B. (NOT move , just Copy)

So its kind of DUPLICATE Forum A to Forum B , exact copy of all threads including all posts inside , just exact copy duplicate all threads from 1 forum to another!

Is there a way to do this? I tried using admin/moderator options but there is NO copy option , only move/delete/and so on ...
Copy option shows up ONLY under EACH THREAD , NOT for mass-thread copying.

How to do this?

Thanks in advance..

P.S: I'm using "vBulletin v3.7.4 Patch Level 1"
