 This guide covers a [**long time deprecated**](/blog/2021/08/21/4.0-deprecation-announcements) and [**in 4.x, removed**](https://github.com/rabbitmq/rabbitmq-server/pull/9815) legacy feature: mirroring (queue contents replication) of classic queues.
 [Quorum queues](./quorum-queues) and/or [streams](./streams) should be used instead of mirrored classic queues.
 
-Quorum queues are a more advanced queue type, which offers high availability using  replication and focuses on data safety. Quorum queues [support message TTL](/blog/2022/05/05/rabbitmq-3.10-release-overview) and provide [higher throughput and more stable latency](/blog/2022/05/16/rabbitmq-3.10-performance-improvements) compared to mirrored classic queues. Please [migrate from Mirrored Classic Queues to Quorum Queues](./migrate-mcq-to-qq) now.

 [Streams](./streams) is an [alternative messaging data structure](/blog/2021/07/13/rabbitmq-streams-overview) supported by RabbitMQ.
 Just like quorum queues, streams are replicated.

 Which is better: mirrored classic queues or quorum queues? [Quorum queues](./quorum-queues) are the much better choice and they will be [the only option starting with RabbitMQ version 4.0](https://blog.rabbitmq.com/posts/2021/08/4.0-deprecation-announcements/).
 This information explains why, the reasons why you should migrate from mirrored classic queues to quorum queues, the ways to handle features during the migration, and includes procedures for some of the migration routes you can take.
