ApsaraDB RDS:Upgrade from Basic Edition to High-availability Edition

This upgrade is irreversible. After the upgrade, the instance cannot be downgraded back to Basic Edition.

For fee details, see Change instance specifications.

Basic Edition vs. High-availability Edition

Prerequisites

Before you begin, make sure that:

• The instance uses the subscription or pay-as-you-go billing method.

  Note

  For instances that use the serverless billing method, follow the instructions in Configure a serverless ApsaraDB RDS for MySQL instance.

• The instance runs MySQL 8.0 or MySQL 5.7 on RDS Basic Edition. Check this on the Basic Information page of the instance.

• The minor engine version is 20211231 or later. To update the minor engine version, see Upgrade the minor engine version.

  Note

  This prerequisite does not apply to MySQL 5.7 Basic Edition instances with standard SSDs that are upgrading to High-availability Edition with Premium Local SSDs.

• The instance is not a read-only instance. Read-only instances cannot be upgraded from Basic Edition to High-availability Edition.

Impact of the upgrade

• The upgrade can trigger a data migration, which may take a few minutes. After the migration is complete, an instance switchover is triggered at the switching time that you specify. Make sure that your application is configured to automatically reconnect to the instance. For more information, see Impacts of an instance switchover.

  Note

  The endpoint of the instance remains unchanged after the upgrade. No changes to application configurations are required.

• After the upgrade completes, the instance cannot be downgraded back to Basic Edition.
