Replicate Existing Cluster
with Amazon ElastiCache · IT Infrastructure Management
Promote an existing cluster into the primary of a new replication group.
- Describe the existing cluster to confirm it exists before building a replication group around it. The CacheClusterId query parameter scopes the description to the single candidate primary cluster.
- Submit a CreateReplicationGroup request that names the verified cluster as the PrimaryClusterId. The Action and Version query parameters identify the AWS operation; the group attributes travel in the form-encoded body.
- Describe the new replication group and confirm it has reached an available status. The ReplicationGroupId query parameter scopes the description to the group just created.
What you'll need to have ready
- PrimaryClusterId: The identifier of the existing cluster to use as the primary.
- ReplicationGroupId: The identifier for the new replication group.
- ReplicationGroupDescription: A user-created description for the replication group.
- AutomaticFailoverEnabled: Whether a read replica is automatically promoted if the primary fails.
