Can I Upgrade Version for a DCS Redis Instance, for Example, from Redis 3.0 to Redis 4.0 or 5.0?
No. Different Redis versions use different underlying architectures. The Redis version used by a DCS instance cannot be changed once the instance is created.
If your service requires the features of higher Redis versions, create a new DCS Redis instance of a higher version and then migrate data from the original instance to the new one. For details on how to migrate data, see the Data Migration Guide.
