I would like to second that. I want to merge 2 wikis and currently I plan to move the whole second wiki to a new namespace of the first wiki as follows:
1. copy content of pages, attic and meta of 2nd wiki to a subfolder (the new namespace) of 1st wiki (minus wiki and playground)
2. for *.changes in the newly created meta subfolder, prepend the namespace to 4th column of every line
3. merge the _dokuwiki.changes according to
http://www.dokuwiki.org/tips:recreate_wiki_change_log
4. delete cache and index, rebuild index with the plugin
Is that all right so far? Am I missing something? What to do with the *.meta and *.indexed files? Can I fix them by hand? Do I need to at all?
Another subtle problem is, that all the files created by dokuwiki belong to the apache user, but as soon as I copy them they belong to my ftp user (I have no root access)...
Any hints appreciated!
