For details about how to change the capacity, see Modifying Specifications.

If you want to use a smaller Proxy Cluster DCS Redis 3.0 instance, back up the data of the existing instance, and create a new Proxy Cluster instance with the desired capacity. Then, import the backup data to the new instance. After the data migration is complete, delete the old instance. For details about data migration operations, see Importing Backup Files.
