ApsaraDB for MongoDB:Update the minor version of an instance

Usage notes

• You cannot downgrade the minor version of an instance after you update the minor version.

• After you update the minor version of an instance, the instance is restarted and is disconnected from your application for less than 30 seconds. We recommend that you perform the minor version update during off-peak hours or make sure that your application can automatically reconnect to the instance.

• If the minor version of your instance is not the latest version, the system may update the minor version to the latest version to ensure higher performance and stability when you perform the following operations:

  Operation	Description
