  • UPGRADE: upgrades the configuration of a subscription instance. This is the default value.
  • DOWNGRADE: downgrades the configuration of a subscription instance.
Note
  • If you change the configuration of a pay-as-you-go instance, this parameter is not required.
  • To downgrade a subscription instance, you must set this parameter to DOWNGRADE.
  • If the price increases after specifications are changed, it is an upgrade configuration. If the price decreases, it is a downgrade configuration. For example, the price of an 8 GB read/write splitting instance with five read replicas is higher than that of a 16 GB cluster instance. If you want to switch a 16 GB cluster instance to an 8 GB read/write splitting instance with five read replicas, you must upgrade the instance.
