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
- Your RDS instance runs RDS Basic Edition, RDS High-availability Edition, or RDS Enterprise Edition. For more information, see Overview
- Your RDS instance belongs to the general-purpose instance family or the dedicated
instance family. For more information, see ApsaraDB RDS instance familiesNote If your RDS instance belongs to the shared instance family, you cannot update the minor engine version of your RDS instance.
Precautions
- 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 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 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 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.

You can use one of the following methods to view the minor engine version of your
RDS instance:
- Log on to the ApsaraDB RDS console and go to the Basic Information page of the RDS instance.
