    For more information about the release notes for minor engine versions of ApsaraDB RDS for SQL Server, see Release notes for minor engine versions of ApsaraDB RDS for SQL Server.

    For more information about how to update the minor engine version of an RDS instance that runs a different database engine, see the following topics:

    Prerequisites

    The RDS instance meets the following requirements:

    • The RDS instance runs RDS Basic Edition, RDS High-availability Edition, or RDS Cluster Edition. Serverless RDS instances are not supported.

    • The RDS instance uses a general-purpose or dedicated instance type. Shared instance types are not supported.

    Note

    Usage notes

    • An update requires several hours to several days based on the data volume of your RDS instance.

    • During the update, a transient connection that lasts approximately 20 to 30 minutes occurs. We recommend that you perform the update during off-peak hours. In addition, make sure that your application is configured to automatically reconnect to your RDS instance. If the write workload is heavy during the update, a longer period of time is required to complete the update.

    • After you update the minor engine version of your RDS instance, you cannot roll the minor engine version of the RDS instance back to the previous version.

      Warning

      Before you perform an update, we recommend that you create an RDS instance that runs the required minor engine version to test overall compatibility. For more information, see Restore the data of an ApsaraDB RDS for SQL Server instance.

    • After you update the minor engine version of your RDS instance, the value of the Backup Size parameter on the Basic Information page of your RDS instance may be displayed as 0. After the next scheduled backup is complete, this error is automatically fixed.

    • In most cases, minor engine version updates do not cause compatibility issues. However, minor engine version updates may cause changes in functionality. We recommend that you check SQL Server CUs released by Microsoft to check whether the SQL Server kernel is updated.

    • During the upgrade, we recommend that you do not modify metadata of your RDS instance. Otherwise, data inconsistency issues may occur after the upgrade. For example, we recommend that you do not create databases, delete databases, or modify the recovery models of databases.
