This topic describes how to update the minor engine version of an ApsaraDB RDS for SQL Server instance. These updates are used to enhance database performance, introduce new features, and fix known bugs.
For more information about the minor engine versions of ApsaraDB RDS for SQL Server, see Release notes of minor ApsaraDB RDS for SQL Server versions.
- An update requires 20 minutes to 30 minutes based on the data volume of your RDS instance. We recommend that you perform an update during off-peak hours. In addition, make sure that your application is configured to automatically reconnect to your RDS instance.
- After you update the minor engine version of your RDS instance, you cannot rollback the update.
Warning Before you perform an update, we recommend that you create an RDS instance that is designed to run the destination minor engine version. Then, migrate the data of your RDS instance to the new RDS instance to test overall compatibility. For more information, see Restore the data to a new RDS instance.
- After you update the minor engine version of your RDS instance, the value of Backup Size on the Basic Information page of the ApsaraDB RDS console may be displayed as 0. After the next scheduled backup is complete, this error is automatically fixed.
