Upgrading the Kernel Version of a Proxy Instance

Upgrade Methods

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

• Upon submission: The system upgrades the minor kernel version upon your manual submission of the upgrade request.
• In maintenance window: The system upgrades the minor kernel version during the maintenance window you have specified. For details about how to change the maintenance window, see Changing the Maintenance Window of a DB Instance.

If the kernel version of your DB instance has potential risks or major defects, has expired, or has been brought offline, the system will notify you by SMS message or email and deliver an upgrade task during the maintenance window.

Precautions

Intermittent disconnections occur during an upgrade. The time required to complete the upgrade depends on how many proxy instances there are. Perform the upgrade during off-peak hours.
