Migrating previous generation nodes - Amazon ElastiCache
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Migrating previous generation nodes

Previous generation nodes are node types that are being phased out. If you have no existing clusters using a previous generation node type, ElastiCache does not support the creation of new clusters with that node type.

Due to the limited amount of previous generation node types, we cannot guarantee a successful replacement when a node becomes unhealthy in your cluster(s). In such a scenario, your cluster availability may be negatively impacted.

We recommend that you migrate your cluster(s) to a new node type for better availability and performance. For a recommended node type to migrate to, see Upgrade Paths. For a full list of supported node types and previous generation node types in ElastiCache, see Supported node types.

Migrating nodes on a Memcached cluster

To migrate ElastiCache (Memcached) to a different node type, you must create a new cluster, which always starts out empty that your application can populate.

To migrate your ElastiCache (Memcached) cluster node type using the ElastiCache Console:
