--replication-group-id
(string)
The ID of the replication group to which data should be migrated.
--customer-node-endpoint-list
(list)
List of endpoints from which data should be migrated. For Redis (cluster mode disabled), list should have only one element.
(structure)
The endpoint from which data should be migrated.
Address -> (string)
The address of the node endpoint
Port -> (integer)
The port of the node endpoint
Shorthand Syntax:
Address=string,Port=integer ...
JSON Syntax:
[
{
"Address": "string",
"Port": integer
}
...
]
--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
See ‘aws help’ for descriptions of global parameters.
To start a migration
The following start-migratio
migrates your data from self-hosted Redis on Amazon EC2 to Amazon ElastiCache, using the Redis engine.
aws elasticache start-migration \
--replication-group-id test \
