How Do I Reduce the Capacity of a DCS Instance?

The following table lists scaling options supported by different DCS instances.

**Table 1** Scaling options supported by different DCS instances
Cache Engine	Single-Node	Master/Standby	Redis Cluster	Proxy Cluster
Redis 3.0	Scaling up/down	Scaling up/down	N/A	Scaling out
Redis 4.0	Scaling up/down	Scaling up/down and replica quantity change	Scaling up/out, down/in, and replica quantity change	N/A
Redis 5.0	Scaling up/down	Scaling up/down and replica quantity change	Scaling up/out, down/in, and replica quantity change	N/A
Redis 6.0	Scaling up/down	Scaling up/down	N/A	N/A
Memcached	Scaling up/down	Scaling up/down	N/A	N/A

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