Migration from moin 1.5.2 to moin 1.5.3
We just make sure that there is a "meta" file in your data directory that
stores the "revision" level of it (so future mig scripts can tell if they
need to run or not [e.g. because you already have run them]).
This is the last "old style" migration script.
Steps for a successful migration:
1. You do NOT need to stop your wiki for this mig script.
2. Change directory to: .../MoinMoin/script/old/migration
3. Run this script as a user who may write to the data_dir of your wiki
and supply the pathes to the data_dir you want to migrate. If you
have multiple wikis, you may specify multiple pathes on the command
line:
sudo -u www-data ./152_to_1050300.py /my/path/to/data
4. That's it.
Future mig scripts now can auto-detect the data_dir revision level.
