Version 3.0.1

    Note

    If you are upgrading a cluster, you must be running CrateDB 2.0.4 or higher before you upgrade to 3.0.1.

    We recommend that you upgrade to the latest 2.3 release before moving to 3.0.1.

    If you want to perform a rolling upgrade, your current CrateDB version number must be at least . Any upgrade from a version prior to this will require a full restart upgrade.

    When restarting, CrateDB will migrate indexes to a newer format. Depending on the amount of data, this may delay node start-up time.

    Warning

    Tables that were created prior to upgrading to CrateDB 2.x will not function with 3.0 and must be recreated before moving to 3.0.x.

    You can recreate tables using and COPY FROM while running a 2.x release into a new table, or by .

    Before upgrading, you should back up your data.
