# Amazon MSK: Apache Kafka 3.7 end of support

End of support date for Apache Kafka 3.7 on Amazon MSK: 1 Sep 2026. After that date, a cluster still using the version is auto-upgraded to the recommended Kafka version.

- Effective date: 1 Sep 2026
- Cloud: [AWS](https://eolwatch.dev/cloud/aws.md)
- Service: [Amazon MSK](https://eolwatch.dev/services/aws/msk.md)
- Type: End of support
- Category: [Service](https://eolwatch.dev/categories/services.md)
- Affected versions: 3.7
- Replacement: Not stated by vendor
- Announced: Not stated by vendor
- Official source: [docs.aws.amazon.com](https://docs.aws.amazon.com/msk/latest/developerguide/supported-kafka-versions.html)
- Last checked: 12 Nov 2026

## What breaks

Amazon MSK supports a Kafka version until its end of support date. After that date:

- A cluster still using the version is auto-upgraded to the recommended Kafka version.
- The automatic upgrade can happen at any time after the end of support date.
- No notification is sent before the upgrade.

For Kafka versions with a published end of support date, AWS states its intent to phase out support for newly created clusters. The page gives no date for this.

## Who is affected

### Affected versions

- `3.7`

### Matching resource types

- `aws_msk_cluster`

### Fields the check reads

- `kafka_version`

### Detected by the estate check from

- Terraform state or plan (JSON)

## What to do

1. Upgrade the MSK cluster to the recommended Kafka version or a higher version before the end of support date. The recommended version is marked in [Supported Apache Kafka versions](https://docs.aws.amazon.com/msk/latest/developerguide/supported-kafka-versions.html).
2. Before upgrading, verify that the version of your client-side software supports the features in the new Kafka version. Server-side upgrades do not automatically update client applications.
3. Follow [Upgrade the Apache Kafka version](https://docs.aws.amazon.com/msk/latest/developerguide/version-upgrades.html) to upgrade with the console, the AWS CLI or the API. The CLI command `aws kafka get-compatible-kafka-versions` lists the versions the cluster can upgrade to.
4. Version downgrades are not supported.
5. See [Best practices for version upgrades](https://docs.aws.amazon.com/msk/latest/developerguide/version-upgrades-best-practices.html).

## Replacement

Not stated by vendor.
