| Because Kafka treats a changed group ID as a brand-new consumer group, connectors using an auto-generated group ID after upgrading will lose their committed offsets and may reprocess messages. | ||
|
|
||
| **Action required:** Before upgrading to 8.9, set an explicit **Consumer Group ID** in each Kafka Consumer connector configuration to preserve consumer group identity. See the [Kafka connector documentation](/components/connectors/out-of-the-box-connectors/kafka.md?kafka=inbound) for details. |

Description
Added an announcement about a potentially breaking change, affecting some users during 8.8-8.9 migration. The change is related to the Kafka connector's default consumer group ID generation strategy that has changed between minors.
Also adjusted the connector docs to emphasize the importance of defining a custom group ID.
When should this change go live?
