Precautions
- The database engine version cannot be downgraded.
- The database engine version can only be upgraded from MySQL 5.5 to MySQL 5.6.
- Before performing a database engine version upgrade, we recommend that you purchase an ApsaradB RDS MySQL instance of the target version to test the version compatibility.
- During a database engine version upgrade, your ApsaraDB RDS MySQL instance may encounter a 30-second transient disconnection. We recommend that you perform the upgrade during off-peak hours or make sure that your application can automatically reconnect to your ApsaradB RDS MySQL instance.
