Amazon MQ now supports in-place major version upgrades for RabbitMQ 4
Amazon Web Services has launched in-place major version upgrades for RabbitMQ brokers in Amazon MQ, allowing customers to upgrade directly from RabbitMQ 3.13 to version 4.2 without requiring data migration or broker recreation. The upgrade process preserves existing broker configurations, queues, exchanges, bindings, user accounts, and policies while transitioning to RabbitMQ 4.2's significant architectural changes. RabbitMQ 4.2 introduces breaking changes including the elimination of classic mirrored queues and a migration from the Mnesia database to the new Khepri metadata store. To be eligible for the upgrade, brokers must run on AWS's M7G Graviton instance types and cannot have any classic mirrored queues configured. AWS provides a queue migration tool to convert classic mirrored queues to quorum queues before the upgrade process begins. The upgrade can be initiated through the AWS Management Console, CLI, or SDKs, with AWS automatically handling patch version management for RabbitMQ 4.2 brokers going forward. During the major version upgrade process, brokers will experience downtime while Amazon MQ performs the transition. The capability is now available in all AWS regions that currently support RabbitMQ 4 instances.
Why It Matters
This upgrade capability addresses a major operational pain point for enterprises running message queuing infrastructure, as traditional RabbitMQ major version upgrades typically require complex data migration procedures and extended downtime. The move to RabbitMQ 4's Khepri metadata store represents a significant architectural shift that improves scalability and performance, while the elimination of classic mirrored queues forces users toward the more robust quorum queue implementation. For organizations heavily invested in RabbitMQ-based messaging architectures, this streamlined upgrade path reduces operational complexity and accelerates adoption of the latest messaging broker capabilities.
