Anything out there I could import a whole idealBB forum's db to?

[Rascally]

Okay, so here's my problem.

My main client's business is a pretty fairly-sized website that's been around a few years. Until this year, it was all on ASP. Just before I came onboard, they moved most of the site over to a Ruby on Rails platform on CentOS. However, a few parts of the site are still on the windows server. One of which is an idealBB installation (not even idealBB.NET). Lately, there's been nothing but problems with it. We've worked at length with the developer, but of course it basically comes down to it's a) old code, pre-.NET and not maintained anymore, and b) just kinda clunky design.

So, we were pondering moving away from idealBB to something else...anything else at this point, frankly. :| However, we don't want to lose the years of forum threads that are still around. So my question is:

- Is there anything out there right now for forum software that will import an SQL database created by idealBB...like, something that'll import the whole thing off the shelf? (I know, wishful thinking)

- Barring that, has anyone out there attempted this feat? If so, what'd you convert to? Was it even more impossible than say, forcing the entire slashdot membership to use windows 98 for the next decade or something? ;)

Any guidance/suggestions/ideas would be REALLY helpful here, guys. I figured if anyone'd have an idea, it's those of us who haunt Neowin. :)

Thanks in advance!!
