Why Migrate with AutoMQ?
Experience the only migration tool designed for zero downtime and absolute data consistency.
Zero Downtime Migration
With AutoMQ
Perform a standard rolling update. Update your cluster client-by-client, one-by-one. Traffic shifts seamlessly with zero service interruption.
The Alternative
Competitors like MirrorMaker require a "Stop the World" cutover, forcing you to halt production traffic and endure unpredictable downtime windows.
100% Flink State Retention
With AutoMQ
Our engine ensures bit-for-bit offset preservation. Your Flink jobs and stateful applications migrate instantly and resume from their last checkpoint.
The Alternative
Other tools break offset mapping, forcing you to discard Flink state, rewind consumer groups, and re-process terabytes of historical data.
Lossless Rollback Safety
With AutoMQ
Change your mind at any stage. You can rollback to the source cluster instantly without losing new data generated during the cutover.
The Alternative
Standard tools reach a "point of no return". Rolling back often means losing data written to the new cluster or facing a messy manual reconciliation.
Zero Operational Complexity
With AutoMQ
Treat migration like a routine deployment. No complex replication setups or manual update/commit steps—just a rolling update.
The Alternative
Traditional migration tools demand high-risk manual operations, requiring strict coordination between infrastructure and application teams to avoid data gaps.

Want to understand how we achieve zero downtime and preserve Flink state? Our engineers can walk you through the technical details.
Built-in Intelligence for Seamless Migration
Kafka Linking is a built-in capability, not an external tool. It automates complex synchronization and client coordination internally to guarantee strict consistency and safety.
Byte-Level Replication
Replicate the raw byte stream, ensuring strict 1:1 offset consistency. Because the target offsets are identical to the source, your Flink checkpoints and application states remain valid—zero data re-processing required.
Smart Write Forwarding
To preserve ordering, writes to the new cluster are temporarily proxied back to the source during migration. This ensures new data lands on the source first, enabling lossless rollbacks if you revert without losing a single message.
Consumer Coordination
To prevent duplication, our coordinator blocks the new consumer's fetch requests until it confirms the old client has disconnected. This "handshake" ensures Exactly-Once semantics throughout the rolling update.
Granular Migration Control
Migration is not "all-or-nothing." You can define tasks at the Topic + Consumer Group level. Move non-critical workloads first to verify stability, then migrate core business lines at your own pace.
