I've a quite big vBulletin forum, with 400'000 messages and 15'000 users. Now I want to disable the vBulletin CMS and install Wordpress in the root of my domain.
So I'll move the forum in a folder (mysite.it/forum/) or in a subdomain (forum.mysite.it). Which is the best solution according to your experience? What do you suggest me to do? Thanks.
