Forum Importers, Converters, Merge System for vBulletin, IPB, myBB, xenForo, and phpBB

I decided to research forum converters and I was very surprised by how much coverage is out there. vBulletin leads the pack with the most converters available at one point or another. Note: Many of those listed may not longer be supported, particularly due to end of life of the other product, or lack of demand.

I've listed the supported importers, converters, and merge systems (they vary in naming from platform to platform) for vBulletin, IPB, myBB, xenForo, and phpBB. With the number of forums out there, this could really be the topic of an entire forum!
