This section contains documents specific to upgrading etcd clusters and applications.

## Upgrade policy

Before upgrading, note that etcd only supports the following two upgrade cases:

* **Patch upgrade:** Upgrading between patch releases within the same minor version (e.g. 3.4.18 - 3.4.20).
* **Minor upgrade:** Upgrading one minor version at a time (e.g. 3.3 - 3.4). Upgrades that skip a minor version are not supported and will likely fail. Update to the most recent patch version before upgrading to the next minor version.

## Moving from etcd API v2 to API v3

* [Migrate applications from using API v2 to API v3][migrate-apps]
