My forums were originally converted from vBulletin 3 to IP. Board 3. I would like to import my forums from IP. Board 3 to XenForo 1. I am concerned about the vBulletin 3 password hashes. I don't know whether members who haven't logged in since the vBulletin days will be able to access their account or not due to this. Is this possible to do? Will there be any issues with the vBulletin 3 data?
