I'm looking to merge a vBulletin forum I'm closing with my more active Xenforo forum. So I'm trying to import the vBulletin 4 data into the existing Xenforo forum. I understand there's an Import External Data option in the ACP, but I need a little help going through this step by step. If someone can point me to a guide or walk me through this, I'd appreciate it. What information am I supposed to fill out for this? A little help please.
