I have two vBulletin 3.8 forums. I'd like to convert and merge both of them into one XenForo installation. Presumably, I would simply import one and then import the other, merge duplicate accounts (of which there would be many), and be on my way. From my understanding of the import documentation, this is supported, but after searching I haven't been able to find much discussion about it. Has anyone tried it in a production environment, and did you have any success?
