Currently we're considering moving the WLUG wiki from PhpWiki (or WlugWiki, as we are really running a fork of PhpWiki by now) to MediaWiki?.
This isn't about pros or cons of either piece of software!
I'm currently working on a script that was originally written by Isaac Wilcox. This does a reasonable first pass on converting the wiki markup, however there's a lot of things it doesn't do yet, mostly involving any old-style wiki markup, which is rife throughout the WLUG wiki.
Also, having migrated the content, every page will need to be visited, and checked for validity, and resaved. This is very important! A lot of the 'special' pages within Mediawiki only get updated when a page gets saved. The Backlinks and Category equivalents are obvious examples. We can let this happen "as the wiki gets used", but the fact is for the new site to work properly we will have to do this. We could, I suppose, write something which simulates editing then saving a page, which will address the automagic pages, but won't confirm the markup was translated completely.
I'm aware that if we aim for 100% conversion we'll probably fail, but what we're probably looking at is approximately 80% of the wiki markup being converted at the moment, and still a requirement to walk across pretty well all of the 7000 odd pages in the wiki.
There's a bunch of plugins we've written - WlugMember? being one of them - that will have to be rewritten. This probably isn't such an onerous chore, as most of the plugins we've written are pretty simple, however it's something that must be taken into account.
We've also added a lot of extensions, such as the spam limiting and google query banner. These will need to be reimplemented. I think MediaWiki? has a much nicer framework for adding these at least - it probably won't involve hacking the theme directly like it did in phpwiki, but this needs to be taken into account.
