Keeping this on mailman-developers since I'm not on all those other lists. ;-)

Our very huge thanks go to Paul Boddie who did the amazing conversion work, almost single-handedly reverse engineering the Confluence dump through several iterations.
Hurray! Well done. Can you publish the dump somewhere on your site, or on archive.org? WikiTeam is very interested in Confluence dumps, any writing/braindump/code on the matter is very welcome. https://github.com/WikiTeam/wikiteam/issues/108
I'll leave this for the others to decide, although it's not that difficult to obtain dumps directly from Confluence yourself. So, even though one might have bad things to say about proprietary services, credit is due to Atlassian for allowing their users to download most of their data (the profile information isn't available through the same mechanism) for deployment in other ways.
The conversion software itself is described here:
My advice to anyone considering migrating from Confluence is to do so in a short timeframe (and as soon as possible if you want the above code to work!) in order to avoid changes in the product disrupting the activity and necessitating more work. For example, while tackling this task, Confluence 4 came out with a completely different page text representation which then had to be parsed and converted.
If you need to know more about this, feel free to ask me directly.
