# Testing the data migration
<a name="Migration-Test"></a>

After all prerequisites are complete, you can validate the migration setup for your node-based ElastiCache cluster using the AWS Management Console, ElastiCache API, or AWS CLI. The following example shows using the CLI.

Test migration by calling the `test-migration` command with the following parameters:
+ `--replication-group-id` – The ID of the replication group to which data is to be migrated.
+ `--customer-node-endpoint-list` – List of endpoints from which data should be migrated. List should have only one element.

The following is an example using the CLI.

```
aws elasticache test-migration --replication-group-id test-cluster --customer-node-endpoint-list "Address='10.0.0.241',Port=6379"
```

ElastiCache will validate migration setup without any actual data migration.
