vB 3.8 Forum Conversion - How Long for 5+ Million Posts?


Well-known member
I'm considering converting my vBulletin 3.8 forum, with approximately 191k users and 5.3 million posts, to XenForo. I was looking at IP.Board, but after toying with IPB 3.2's converter script, I found it would take an unreasonably and unacceptably long amount of downtime (several days) to actually make the switch.

Could anyone offer a general estimate as to how long this process would take with XF?
