I have an old private Mediawiki install that can not be updated directly. I would like to decommission it but first export all of its pages from all of its namespaces (including all User pages, all Talk pages and all pages and talk pages from custom namespaces) and import them into a fresh, new modern MW-1.30 wiki that has the same set of registered users and the same set of namespaces. --- I would also like to export all revision histories as well. I think this is possible with the "dumpBackup.php", but I'm not sure what switches I need to set (if any) to get the revision histories and all of the custom namespaces in one command? Anyone have experience doing this?
