Version 3.1.5¶
Released on 2019/01/14.
Note
If you are upgrading a cluster, you must be running CrateDB 2.0.4 or higher before you upgrade to 3.1.5.
We recommend that you upgrade to the latest 3.0 release before moving to 3.1.5.
If you want to perform a rolling upgrade, your current CrateDB version number must be at least Version 3.1.1. Any upgrade from a version prior to this will require a full restart upgrade.
Warning
Tables that were created prior to upgrading to CrateDB 2.x will not function with 3.1 and must be recreated before moving to 3.1.x.
You can recreate tables using COPY TO
and COPY FROM
while running a
2.x release into a new table, or by inserting the data into a new table.
Before upgrading, you should back up your data.
