Chris Egerton commented on KAFKA-15985:
---------------------------------------
[~Reamer] Can you share your MM2 configuration (feel free to scrub any
sensitive properties)? I'm especially interested in the value of the
{{offset.lag.max}} property, though other properties may also be relevant here.

> Project: Kafka
> Issue Type: Bug
> Affects Versions: 3.5.1
> Reporter: Philipp Dallig
> Priority: Major
>
> 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

> source cluster.
