# Update a topic in an Amazon MSK cluster
<a name="msk-update-topic"></a>

Update the partition count or topic-level configurations for an existing topic. This operation modifies the topic without requiring recreation.

**Note**  
You can update either the partition count or the topic configurations in a single API call, but not both simultaneously. To update both, make separate API calls.
