A couple of seed documents have been born from that project:
http://ebiotic.net/bin/MigrationCode/HowToMigrate http://ebiotic.net/bin/Draft/MigrationCheckList I think that at least one of them could be moved to a convenient place in the xwiki.org farm, but I've had no time yet to follow this thread. Perhaps they could be useful for you even in their current state. Also, I must update this installation to the current available XE/XEM release. I think this page could also be checked to see how the XWiki team is getting XWiki farm updated! http://www.xwiki.org/xwiki/bin/view/XWiki/Migrations Hope this helps!
