+Template: rabbitmq-server/mnesia-dir-note
+Type: note
+Description: Schema changed
+ The RabbitMQ database schema has changed. If your RabbitMQ database contains important data, such as user accounts, durable exchanges and queues, or persistent messages, then we recommend you contact support@rabbitmq.com for assistance with the upgrade. If you want to experiment with the new version in the meantime, simply move the database directory to a safe place. In all other cases just remove the directory.
