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

Kafka migrations get talked about like they're impossible. They aren't. They're a sequence of decisions plus a working playbook.

In this session, Eero and Dirk run a real Confluent Cloud-to-Aiven migration top to bottom. You see how to size the source cluster, replicate topics and consumer group offsets with MirrorMaker 2, handle schema IDs through Karapace, and stage a cutover that keeps producers and consumers running.

Along the way: what breaks first at scale: Confluent auth modes (OAuth, mTLS, API key), RBAC vs Kafka-native ACLs, custom serializers, CSFLE-encrypted payloads - and how to handle each. You walk out with a runbook, not a slide deck.
