[xwiki-users] Exporting a space

Would welcome some advice on how to export the contents of an entire space so that it can be imported into a different XWiki instance. I looked at this: http://platform.xwiki.org/xwiki/bin/view/Features/Exports and reading between the lines thought that a URL like this should do the trick: http://localhost:8080/xwiki/bin/export/Space/Page?format=xar&pages=MySpace.%... It does indeed generate a MySpace.xar file, but its contents are not what are desired. Just a single page called %.xml I also noticed this extension: http://extensions.xwiki.org/xwiki/bin/view/Extension/Multipage+Export+Applic... Maybe that can do the trick. Advice welcome. Surely this needs to be done all the time so must be easily solvable? Tim
