Until now, you could already upgrade minor versions of CrateDB directly yourself in the CrateDB Cloud Console. Now we have enabled major version upgrades as well, letting you upgrade major versions of our database using the convenience of our Cloud UI. For example, you can use this functionality to take full advantage of the CrateDB 5.0 release, getting the most out of our service at a time convenient to you.
Like minor version upgrades, the major version ones can be performed either in the CrateDB Cloud Console or using the Croud CLI. Note that one must have first upgraded to the latest possible minor version release to do a major version upgrade: e.g., going from 4.8 to 5.0 works directly, but not from 4.7 to 5.0 - this requires a minor version upgrade to 4.8 first.
