Hello A new version of the Nested Pages Migrator Application extension is available. See http://extensions.xwiki.org/xwiki/bin/view/Extension/Nested+Pages+Migrator+… <http://extensions.xwiki.org/xwiki/bin/view/Extension/Tour+Application#Hv1.0> You can install or upgrade with the Extension Manager. The application is still a beta version that you should use carefully. XWiki crashes might occur during the migration. But this version brings the ability to detect bad documents created because of these crashes so you are able to finish the migration by restarting XWiki (several times if needed). It is still not a friendly process, but at least it is possible and I know it will help some peoples. It also brings an icon in the applications panel :) Enjoy! -- Guillaume Delhumeau (guillaume.delhumeau(a)xwiki.com) Research & Development Engineer at XWiki SAS Committer on the XWiki.org project
