{{% capture overview %}}
`kubeadm upgrade` is a user-friendly command that wraps complex upgrading logic behind one command, with support
for both planning an upgrade and actually performing it. `kubeadm upgrade` can also be used for downgrading
cluster if necessary.

## kubeadm upgrade guidance

Every upgrade process might be a bit different, so we've documented each minor upgrade process individually.
For more version-specific upgrade guidance, see the following resources:

 * [1.7.x to 1.7.y upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-8/)
 * [1.7 to 1.8 upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-8/)
 * [1.8.x to 1.8.y upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-8/)
 * [1.8.x to 1.9.x upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-9/)
 * [1.9.x to 1.9.y upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-9/)
 * [1.9.x to 1.9.y HA cluster upgrades](/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-ha/)

In Kubernetes v1.11.0 and later, you can use `kubeadm upgrade diff` to see the changes that would be
applied to static pod manifests.
