Upgrading the Minor Version of a Standard HTAP Instance

You can upgrade the minor version of your standard HTAP instance to improve performance, optimize functions, and fix bugs.

A minor version can be upgraded in either of the following ways:

Upon submission: The system upgrades the minor version upon your manual submission of the upgrade request.
In maintenance window: The system upgrades the minor version during the maintenance window you have specified.

When any new minor version is released, upgrade the minor version of your standard HTAP instance immediately or during the maintenance window.
The upgrade will cause the standard HTAP instance to reboot and will interrupt services intermittently. To minimize the impact of the upgrade, perform the upgrade during off-peak hours, or ensure that your applications support automatic reconnection.
A minor version upgrade cannot be rolled back after the upgrade is complete.
Before upgrading a minor version, check whether there are temporary data synchronization tasks. If there are, wait until the tasks are complete or manually delete the temporary tasks.
