changing internal links to a new domain?
 

I'm moving a domain and I want to change all internal links in posts, most of the links are absolute links, like http://www.vbulletin.com/forum/forumdisplay.php?f=139, lets say I'm moving to vb.com and I want to change all the places in the post table that contains http://www.vbulletin.com/forum to http://vb.com/forum
how do I do that? (I have a pretty big post table..)

so after the process I'll have working internal links \ hyperlinks etc' to my new domain.

thanks.
