After a new minor version for an engine is released, you can upgrade the engine of your Lindorm instance to the latest minor version in the Lindorm console with a few clicks. A minor version upgrade provides optimizations for the features of the existing minor version and additional new features.
Prerequisites
A Lindorm instance is created. For more information, see Create an instance.
Usage notes
The operation of upgrading the minor version cannot be undone. We recommend that you upgrade the minor version to a stable version first.
When you upgrade the minor version for an instance, the instance must be restarted to make the upgrade take effect. We recommend that you upgrade the minor version during off-peak hours or make sure that your application can automatically reconnect to your instance.
The upgrade duration varies based on the number of instances that are deployed in a region. A large number of instances indicates a long upgrade duration.
Procedure
Log on to the Lindorm console.
In the upper-left corner of the page, select the region where the instance is deployed.
On the Instances page, click the ID of the instance that you want to manage or click Manage in the Actions column corresponding to the instance.
In the Configurations section, find the engine that you want to upgrade and click the
icon in the Actions column corresponding to the engine. Click Upgrade Minor Version.
NoteYou can click the
icon corresponding to each engine to view the description of the engine version of the instance. In the Upgrade Minor Version dialog box, select Latest Version or Stable Version as the minor version to which you want to upgrade the existing minor version.
ImportantYou can select the minor version to which you want to upgrade only for LindormTSDB. For other engines, the minor version is upgraded to the latest version by default.
The operation of upgrading the minor version cannot be rolled back. We recommend that you upgrade the minor version to a stable version.
Click OK.
