  • Snapshot-based downgrades

    The snapshot repository format changed in a manner that prevents earlier versions of Elasticsearch from reading the repository contents if it contains snapshots from this version and the last cluster to write to this repository was in the 8.10 series. This will prevent you from reverting an upgrade to the 8.10 series by restoring a snapshot taken before the upgrade.

    Snapshot repositories written by clusters running versions 8.11.0 and later are compatible with all earlier versions. Moreover, clusters running version 8.11.0 or later will also automatically repair the repository format the first time they write to the repository to take or delete a snapshot, making it so that all earlier versions can read its contents again.

    If you wish to downgrade to a version prior to 8.9.0, take or delete a snapshot using a cluster running version 8.11.0 or later to repair the repository format first. If you cannot repair the repository in this way, first delete all the snapshots in the repository taken with version 8.9.0 or later. To do this will require using a cluster running version 8.10.0 or later.

    If you wish to downgrade to a version in the 8.9 series, you must take or delete a snapshot using a cluster running version 8.11.0 or later to repair the repository format first. If you cannot repair the repository in this way, first delete all the snapshots in the repository taken with version 8.10.0 or later using a cluster running version 8.10.4.
