// Anytime you change the schema of one of the collection in a non-backward
// compatible way you have to write a migration in this file using the following
// API:
//
// Migrations.add(name, migrationCallback, optionalOrder);
// In the context of migration functions we don't want to validate database
// mutation queries against the current (ie, latest) collection schema. Doing
// that would work at the time we write the migration but would break in the
// future when we'll update again the concerned collection schema.
//
// To prevent this bug we always have to disable the schema validation and
// argument transformations. We generally use the shorthandlers defined below.
