 +=== PLUGIN_SQLITE_DATABASE_UPGRADE ===
 +
 +This event is triggered when a new migration (see above) is applied. This makes it possible to do more complex migrations that require more than just SQL.
 +
 +The provided data looks like this: 
 +
 +<code php>
 +$data = array(
 +    'from' => 5, // previous version
 +    'to' => 6, // version this migration migrates to
 +    'file' => /some/path/to/plugin/db/update0006.sql, // the associated update file
 +    'sqlite' => $this // the initialized sqlite plugin instance for this database
 +);
 +</code>
 +
 +
 +The ''BEFORE'' event is executed before the migration file is applied. The default action is to apply that file and increase the ''dbversion'' field in the ''opts'' table.
 +
 +When an event prevents the default, the proper ''$event->result'' has to be set! When the result is true, the ''dbversion'' is increased and any additional migrations are run. When the result is false, the migration process is aborted.
 +
 +The ''BEFORE'' event can optionally change the ''file'' attribute of the data to load a different file.
 +
 +The ''AFTER'' event is only triggered after the migration file has been applied or the ''BEFORE'' event set a truish result. At the ''AFTER'' time, the ''dbversion'' has already been increased.
