| Control Center 2.2.x       | Confluent Platform 7.5.11, 7.6.8 through 8.0.x <sub>\*</sub>              | June 11, 2025    | December 11, 2025      | June 11, 2027             |
| Control Center 2.1.0       | Confluent Platform 7.5.11, 7.6.8 through 7.9.x <sub>\*</sub>              | May 23, 2025     | November 23, 2025      | May 23, 2027              |
| Control Center 2.0.0       | Confluent Platform 7.5.11, 7.6.8 through 7.9.x <sub>\*</sub>              | May 15, 2025     | November 15, 2025      | May 15, 2027              |

Footnotes:
: - <sub>\*</sub> For Confluent Platform 7.5, Control Center only supports patch version: 7.5.11
  - <sub>\*</sub> For Confluent Platform 7.6, Control Center only supports patch version: 7.6.8

Considerations:
: - Control Center is backward compatible with the preceding list of supported Confluent Platform versions
  - Control Center requires a minimum of Java 17
  - If you can’t upgrade to Java 17, consider using Control Center (Legacy) which requires Java 11
  - Use Confluent Platform 7.9 to export metrics with mTLS (communication between Kafka and Control Center)
  - Use Confluent Platform 7.7, or Confluent Platform 7.8 to export metrics with TLS and Basic Auth (communication between Kafka and Control Center)
  - Confluent Platform 8.0 and higher supports only KRaft mode.
  - For ZooKeeper, use a supported version of Confluent Platform from Confluent Platform 7.9 or earlier

## System requirements

Control Center monitors larger workloads compared to previous versions of Control Center (Legacy).

For monitoring clusters with 100k replicas or less (most common):

- Memory: 8 GB
- Storage: 200 GB (preferably SSD)
- CPU: 4 cores

For monitoring clusters with more than 100k replicas:

- Memory: 16 GB
- Storage: 300 GB (preferably SSD)
- CPU: 8 cores

For monitoring clusters with 200k - 400k replicas, use the configurations
mentioned in the [multi-node manual install](multi-node.md#install-c3-multi-node-manual). Alternatively,
adjust the allocated memory, storage, and CPU parameters to accommodate the increased workload.

**Considerations**:

* Storage requirements are based on default metrics retention of 15 days. If you
  configure a different retention, you must proportionately adjust storage.

  For example:
  - If you set metric retention from 15 to 30 days, you should double storage
  - If you set metric retention from 15 to 7 days, you should halve storage
* You can [configure](configuration.md#controlcenter-configuration) the default Control Center network port.
* Using a proxy to control and secure access to Control Center is supported.
