make backups before using this.

XXX: All your data will be lost IF you run the test suite with a

to a different database than in your usual deployment.ini or
development.ini file because all database tables are dropped a

one of these that applies:
``python batch-scripts/upgrade/upgrade_from_v072.py deployment.ini``
``python batch-scripts/upgrade/upgrade_from_v080.py deployment.ini``
XXX: For search to work, we depend on a number of MySQL triggers which
copy the data from our InnoDB tables to a MyISAM table for its
fulltext indexing capability. Triggers can only be installed with
a mysql superuser like root, so you must run the setup_triggers.sql
script yourself.
