Basically, using my thrice-proven method, you'll have to remove Wiki,
DFWiki and Wiki Book (aka Inventory) completely, then install NWiki
(New Wiki).
DFWiki had a cool automatic file sorter thingy that
put all the files and folders where they belonged the second you
unzipped. NWiki does not, so you've got to do it manually. Don't forget
to put the lang files in your lang folder. The default language is
en_utf8.
Remember to back up (export) your
database before you
do anything else. You should also back up or rename (I suggest
renaming: saves a step or two) your dfwiki tables if you have data on
them (e.g., mdl_dfwiki -> mdl_dfwiki1).
Once you have nwiki
installed, you will want to delete mdl_wiki, mdl_wiki_pages and
mdl_wiki_synonymous and rename the dfwiki tables to wiki tables (e.g.,
mdl_dfwiki1 -> mdl_wiki).
All of your dfwikis will have been
deleted, so now you will have to go and create corresponding nwikis in
their stead. Once you have created a nwiki where you once had a dfwiki,
go into the database, note the id number of the nwiki, delete the
nwiki, go to the corresponding dfwiki (now a homeless nwiki) and change
its id number to match that of the deleted nwiki.
Now go back to
the course and open the nwiki. If you're lucky, all the corresponding
dfwiki pages will now be part of the nwiki. If your'e not so lucky, you
will have a blank nwiki with the first page named after the first page
of the dfwiki you are trying to "migrate". Never fear.
The
solution to this problem is very simple. Go back to the database. Open
and browse the table mdl_course_modules. Find the record associated
with the migrated dfwiki in question, open it and change the number in
the field
instance to the old dfwiki id. This will give the nwiki access to all the pages in that dfwiki.
Any problems, drop a line.
Of
course, I'm assuming you have access to the database. If you don't,
then you won't be able to use my method. Too bad, you'll be missing a
ton of fun.
