**Important Upgrade Notes For Volume Snapshot Users**

Starting with DigitalOcean Kubernetes 1.18, alpha versions of [volume snapshots](https://kubernetes.io/docs/concepts/storage/volume-snapshots/) are no longer supported. If existing volume snapshots meet the upgrade requirements, they will be converted automatically to the beta version of a volume snapshot when upgrading a cluster to 1.18.

Alpha versions of volume snapshots can continue to be used with versions prior to 1.18.

Consult the [volume snapshots migration notes](https://docs.digitalocean.com/products/kubernetes/details/volume-features/index.html.md#volume-snapshots-migration-from-alpha-to-beta) before upgrading.
