 Component Previous Current Description
Update your API server and associated master components by using the [IBM Cloud console](https://cloud.ibm.com/login) or running the CLI ibmcloud oc cluster master update[command](https://cloud.ibm.com/docs/openshift?topic=openshift-kubernetes-service-clics_cluster_update).
5. Wait a few minutes, then confirm that the update is complete. Review the API server version on the IBM Cloud clusters dashboard or run ibmcloud oc cluster ls.
6. Install the version of the [oc cli](https://cloud.ibm.com/docs/containers?topic=containers-cli-install) that matches the API server version that runs in the master. Kubernetes does not support oc client versions that are two or more versions apart from the server version (n +/- 2).



When the master update is complete, you can update your worker nodes, depending on the type of cluster infrastructure provider that you have.



* [Updating classic worker nodes](https://cloud.ibm.com/docs/openshift?topic=openshift-updateworker_node).
* [Updating VPC worker nodes](https://cloud.ibm.com/docs/openshift?topic=openshift-updatevpc_worker_node).









 Updating classic worker nodes 

You notice that an update is available for your worker nodes in a [classic infrastructure](https://cloud.ibm.com/docs/openshift?topic=openshift-infrastructure_providers) cluster. What does that mean? As security updates and patches are put in place for the API server and other master components, you must be sure that the worker nodes remain in sync. You can make two types of updates: updating only the patch version, or updating the major.minor version with the patch version.

Applies to only classic clusters. Have a VPC cluster?
