* Ensure that all machine config pools (MCPs) are running and not paused. Nodes associated with a paused MCP are skipped during the update process. You can pause the MCPs if you are performing a canary rollout update strategy.
* If your cluster uses manually maintained credentials, ensure that the Cloud Credential Operator (CCO) is in an upgradeable state.

* If your cluster uses manually maintained credentials with the AWS Secure Token Service (STS), obtain a copy of the `ccoctl` utility from the release image being upgraded to and use it to process any updated credentials. For more information, see xref:../authentication/managing_cloud_provider_credentials/cco-mode-sts.adoc#sts-mode-upgrading[_Upgrading an OpenShift Container Platform cluster configured for manual mode with STS_].
* Ensure that you address all `Upgradeable=False` conditions so the cluster allows an upgrade to the next minor version. You can run the `oc adm upgrade` command for an output of all `Upgradeable=False` conditions and the condition reasoning to help you prepare for a minor version upgrade.

* Ensure that you address all `Upgradeable=False` conditions so the cluster allows an upgrade to the next minor version. An alert displays at the top of the *Cluster Settings* page when you have one or more cluster Operators that cannot be upgraded. You can still upgrade to the next available patch update for the minor release you are currently on.
