A couple of days ago, I did a dist-upgrade on my server which runs Debian. I'm not sure what version I had prior to the upgrade, but after the upgrade I'm at 1.6.2. The problem is that the wiki syntax is different, so my wiki data was mildly hosed. I ended up spending 45 minutes to an hour trying to figure out how to migrate the data.

The magic script is /usr/share/python-support/python-moinmoin/MoinMoin/script/moin.py . You need to run it like this:

$ ./moin.py --config-dir=/path/to/wikiconfig.py/dir/ migration data

The other problem I had is that I had no meta file in my data directory and so the moin.py script would die with a stack trace like this:

Traceback (most recent call last):
  File "./moin.py", line 24, in ?
    run()
  File "./moin.py", line 15, in run
    MoinScript().run(showtime=0)
  File "./../../MoinMoin/script/__init__.py", line 138, in run
    self.mainloop()
  File "./../../MoinMoin/script/__init__.py", line 251, in mainloop
    plugin_class(args[2:], self.options).run() # all starts again there
  File "./../../MoinMoin/script/__init__.py", line 138, in run
    self.mainloop()
  File "./../../MoinMoin/script/migration/data.py", line 44, in mainloop
    curr_rev = meta['data_format_revision']
  File "./../../MoinMoin/wikiutil.py", line 472, in __getitem__
    return dict.__getitem__(self, key)
KeyError: 'data_format_revision'

I assumed that I had some version of 1.5 previously and so I created a meta file with this in it:

data_format_revision: 01050800

After doing that, the moin.py script worked nicely and all my wiki data is in the correct syntax now.
