• Creating a cluster

  Clusters of the earlier versions 5.5.1, 6.2.3, 6.5.4, 7.1.1, and 7.9.3 have been brought offline and cannot be created on the console.

• Upgrading a cluster

  Same version upgrade and cross-version upgrade are supported.

  Same version upgrade is to upgrade the kernel patch of a cluster to fix problems or optimize performance.

  Cross-version upgrade is to upgrade the cluster version to enhance functions or incorporate versions. The supported target version varies according to the current cluster version. For details, see Version Restrictions.

Version Constraints

• After a cluster is upgraded, it cannot be rolled back to an earlier version.
• Elasticsearch clusters of version 5.5.1 cannot be upgraded.
