= Checking the status of an upgrade

[role="_abstract"]
When performing an upgrade (or downgrade), you can check it completed successfully in the status of the `Kafka` custom resource.
The status provides information on the Strimzi and Kafka versions being used.

To ensure that you have the correct versions after completing an upgrade, verify the `kafkaVersion` and `operatorLastSuccessfulVersion` values in the Kafka status.  

* `operatorLastSuccessfulVersion` is the version of the Strimzi operator that last performed a successful reconciliation.
* `kafkaVersion` is the version of Kafka being used by the Kafka cluster.
* `kafkaMetadataVersion` is the metadata version used by Kafka clusters. 

You can use these values to check an upgrade of Strimzi or Kafka has completed.
