Mirror, Cut Over, Move On: A Live Kafka Migration from Confluent to Aiven

Jun 16, 2026

Kafka migrations get talked about like they're impossible. They aren't. They're a sequence of decisions, preparations, and good compromises - plus a working playbook.

In this session, Dirk runs a real Confluent Cloud-to-Aiven migration live. Top to bottom: target Kafka cluster deployment, MirrorMaker 2 setup, replication flow and offset handling, and a staged cutover that keeps producer and consumer downtime to almost zero.

He also walks through the proprietary pitfalls that break migrations first at scale, and how to handle each. The session ends with a runbook you can use to scope, plan, and price your own migration.
