The method to change from cloud disk (standard SSD or ESSD) to local disk depends on the database engine, edition, and current storage type.
Upgrade path: MySQL 5.7 Basic Edition with standard SSDs
If the instance runs MySQL 5.7 on RDS Basic Edition and uses standard SSDs, change the storage type to local disk by upgrading to RDS High-availability Edition through a specification change.
For detailed steps, see Change the specifications of an ApsaraDB RDS for MySQL instance.
Migration path: all other configurations
For instances that do not meet the conditions above, direct storage type change is not supported. Create a new instance with local disks and migrate data:
