(Brion Vibber vibber@aludra.usc.edu): [Configuration info]
Here's a thought: when we get the new server up, let's install the English wiki cleanly from the distribution, make sure it's all happy, then do the switch, _leaving the foreign wikis on the old server_ for a while, then do the same thing for each of the foreign ones in turn, updating them to the newest software, and making everything in sync, before we shut down apache on the old server.
Any problems with that?
