Request Syntax
client.complete_migration(
ReplicationGroupId='string',
Force=True|False
)
string
[REQUIRED]
The ID of the replication group to which data is being migrated.
boolean
Forces the migration to stop without ensuring that data is in sync. It is recommended to use this option only to abort the migration and not recommended when application wants to continue migration to ElastiCache.

Response Structure
(dict) --
ReplicationGroup (dict) --
Contains all of the attributes of a specific Redis replication group.
ReplicationGroupId (string) --
The identifier for the replication group.
Description (string) --
The user supplied description of the replication group.
Status (string) --
The current state of this replication group - creating, available, modifying, deleting, create-failed, snapshotting.
PendingModifiedValues (dict) --
A group of settings to be applied to the replication group, either immediately or during the next maintenance window.
PrimaryClusterId (string) --
The primary cluster ID that is applied immediately (if --apply-immediately was specified), or during the next maintenance window.
AutomaticFailoverStatus (string) --
Indicates the status of Multi-AZ with automatic failover for this Redis replication group.
Amazon ElastiCache for Redis does not support Multi-AZ with automatic failover on:
Redis versions earlier than 2.8.6.
Redis (cluster mode disabled): T1 node types.
Redis (cluster mode enabled): T1 node types.
Resharding (dict) --
The status of an online resharding operation.
SlotMigration (dict) --
Represents the progress of an online resharding operation.
ProgressPercentage (float) --
The percentage of the slot migration that is complete.
MemberClusters (list) --
The names of all the cache clusters that are part of this replication group.
(string) --
NodeGroups (list) --
A list of node groups in this replication group. For Redis (cluster mode disabled) replication groups, this is a single-element list. For Redis (cluster mode enabled) replication groups, the list contains an entry for each node group (shard).
(dict) --
Represents a collection of cache nodes in a replication group. One node in the node group is the read/write primary node. All the other nodes are read-only Replica nodes.
NodeGroupId (string) --
The identifier for the node group (shard). A Redis (cluster mode disabled) replication group contains only 1 node group; therefore, the node group ID is 0001. A Redis (cluster mode enabled) replication group contains 1 to 90 node groups numbered 0001 to 0090. Optionally, the user can provide the id for a node group.
Status (string) --
The current state of this replication group - creating, available, etc.
PrimaryEndpoint (dict) --
The endpoint of the primary node in this node group (shard).
Address (string) --
The DNS hostname of the cache node.
Port (integer) --
The port number that the cache engine is listening on.
ReaderEndpoint (dict) --
The endpoint of the replica nodes in this node group (shard).
Address (string) --
The DNS hostname of the cache node.
Port (integer) --
The port number that the cache engine is listening on.
Slots (string) --
The keyspace for this node group (shard).
NodeGroupMembers (list) --
A list containing information about individual nodes within the node group (shard).
(dict) --
Represents a single node within a node group (shard).
CacheClusterId (string) --
The ID of the cluster to which the node belongs.
CacheNodeId (string) --
The ID of the node within its cluster. A node ID is a numeric identifier (0001, 0002, etc.).

Port (integer) --
The port number that the cache engine is listening on.
PreferredAvailabilityZone (string) --
The name of the Availability Zone in which the node is located.

SnapshottingClusterId (string) --
The cluster ID that is used as the daily snapshot source for the replication group.
AutomaticFailover (string) --
Indicates the status of Multi-AZ with automatic failover for this Redis replication group.
Amazon ElastiCache for Redis does not support Multi-AZ with automatic failover on:
Redis versions earlier than 2.8.6.
Redis (cluster mode disabled): T1 node types.

Example: 05:00-09:00
If you do not specify this parameter, ElastiCache automatically chooses an appropriate time range.

A flag indicating whether or not this replication group is cluster enabled; i.e., whether its data can be partitioned across multiple shards (API/CLI: node groups).
Valid values: true | false
CacheNodeType (string) --
The name of the compute and memory capacity node type for each node in the replication group.
AuthTokenEnabled (boolean) --
A flag that enables using an AuthToken (password) when issuing Redis commands.
Default: false
TransitEncryptionEnabled (boolean) --
A flag that enables in-transit encryption when set to true.
You cannot modify the value of TransitEncryptionEnabled after the cluster is created. To enable in-transit encryption on a cluster you must set TransitEncryptionEnabled to true when you create a cluster.
Required: Only available when creating a replication group in an Amazon VPC using redis version 3.2.6, 4.x or later.
Default: false
AtRestEncryptionEnabled (boolean) --
A flag that enables encryption at-rest when set to true.
You cannot modify the value of AtRestEncryptionEnabled after the cluster is created. To enable encryption at-rest on a cluster you must set AtRestEncryptionEnabled to true when you create a cluster.
