.. _version_6.2.11:

==============
Version 6.2.11
==============

Released on 2026-07-06.

.. NOTE::

    If you are upgrading a cluster, you must be running CrateDB 5.0.0 or higher
    before you upgrade to 6.2.11.

    We recommend that you upgrade to the latest 6.1 release before moving to
    6.2.11.

    A rolling upgrade from >= 6.1.2 to 6.2.11 is supported. Doing a rolling
    upgrade from an earlier version than 6.1.2 can cause runtime errors when
    executing statements relying on implicit casts.

    Before upgrading, you should `back up your data`_.

.. WARNING::

    Tables that were created before CrateDB 5.x will not function with 6.x
    and must be recreated before moving to 6.x.x.

    You can recreate tables using ``COPY TO`` and ``COPY FROM`` or by
    `inserting the data into a new table`_.
