--------------------------------------
Summary: Mirrormaker 2 offset sync is incomplete
Key: KAFKA-15985
URL: https://issues.apache.org/jira/browse/KAFKA-15985
Project: Kafka
Issue Type: Bug
Affects Versions: 3.5.1
Reporter: Philipp Dallig
We are currently trying to migrate between two Kafka clusters using Mirrormaker2
new kafka cluster version: 7.5.2-ccs
old kafka cluster version: kafka_2.13-2.8.0
The Mirrormaker 2 process runs on the new cluster (target cluster)
My main problem: The lag in the target cluster is not the same as in the source
cluster.
