# Upgrade {{es}} [upgrading-elasticsearch]

An {{es}} cluster can be upgraded one node at a time so upgrading does not interrupt service. Running multiple versions of {{es}} in the same cluster beyond the duration of an upgrade is not supported, as shards cannot be replicated from upgraded nodes to nodes running the older version.
This document provides the detailed steps for performing a rolling upgrade of a self-managed {{es}} cluster. A rolling upgrade allows you to upgrade your cluster one node at a time without interrupting service. Running multiple versions of {{es}} in the same cluster beyond the duration of an upgrade is not supported, as shards cannot be replicated from upgraded nodes to nodes running the older version.

:::{note}
Upgrading from a release candidate build, such as 9.0.0-rc1, is unsupported. Use pre-releases only for testing in a temporary environment.
