The LavinMQ definitions file consist of users, queues, exchanges, bindings, virtual hosts, permissions, and parameters. These definitions can be exported to a file to import into another server or used for a schema backup.
What is the definitions file?

Can the definitions file be exported and imported?
Yes, it can be exported to a JSON object, and imported as a JSON object.
Why do I need to export the definitions file?
An exported definitions file can be used to restore the basic setup on a secondary LavinMQ server. It might be used when creating a backup or moving from one AMQP-server to another.
How to export or import LavinMQ configuration
Definitions can be exported or imported as a JSON using any of the following methods:
- The LavinMQ management interface
- Using lavinmqctl commands export_definitions and import_defintions
- Calling the api/definitions API endpoint
Note: Be aware that the exported definitions contain hashed passwords.

Importing definitions is done using
lavinmqctl import_definitions <file>
