Changing Domains - Need to replace cureent domain reference in posts

[SemperFidelis]

Ok
Here is what I need to do.

Im currently in the process of moving my forum from one domain to another.

My current forum has a buckload of threads with images that were uploaded by the members via an upload script (thanks to vb.org).

In the threads themselves the IMG tag is used to point to the location the image was uploaded to.
e.g.
[I M G]http://www.current-domain/forums/uploads/member-name/image01.jpg[/ I M G]

Now what I need to do is be able to replace every instance of :
http://www.current-domain
to
http://www.new-domain
without manually going into each and every thread to do so.
(as you can imagine that would take hours, if not days)

Any suggestions on how to go about this would be greatly appreciated.
