Has anyone here tried taking a crusty old MySQL 3.23 database and upgrading it all the way to MySQL 5 or 5.1? I've found a little bit of info on this but not a whole lot. What I've read so far is that it's best to not skip a major version number when upgrading. So I would have to go from 3.23 -> 4.xx -> 5.
If anyone out there has direct experience and some advice, I'd love to hear from you.
