I currently use vBulletin 4 and am considering converting to XenForo. I know that these forums used to be run on vB and have made the switch to XenForo, with everything still being tied together with aMember. Are there any tips on how to do the transition? Do you first convert vB to XenForo? And then how do you get all the users synced into aMember again? It seems a little tricky! Any advice on how to do this would be awesome.
