I've upgraded the 'Nostalgia Wikipedia', a copy of the English Wikipedia
database from December 2001, to MediaWiki 1.5 as an initial test of our
upgrade infrastructure:
http://nostalgia.wikipedia.org/wiki/Special:Version
(Editing is disabled, and it's running the nostalgia skin, so you can
look but not touch. :)
We'll be hitting a few more over the next few hours, including Commons.
After some more live testing to work out kinks, the remaining wikis will
get upgraded bit by bit over the coming days.
