The following command creates a replication task to copy data from one DB instance behind a DMS endpoint to another using a replication instance::

  aws dms create-replication-task --replicationtask-identifier my-replication-task --target-endpoint-arn arn:aws:dms:us-east-1:123456789012:endpoint:HTWNT57CLN2WGVBUJQXJZASXWE --source-endpoint-arn arn:aws:dms:us-east-1:123456789012:endpoint:ZW5UAN6P4E77EC7YWHK4RZZ3BE --replication-instance-arn arn:aws:dms:us-east-1:123456789012:rep:6UTDJGBOUS3VI3SUWA66XFJCJQ --migration-type full-load --table-mappings 'file://table-mappings.json'

The file ``table-mappings.json`` is a JSON document in the current folder that specifies table mappings::

  {
    "TableMappings": [
      {
        "Type": "Include",
        "SourceSchema": "company",
        "SourceTable": "emp%"
      },
      {
        "Type": "Include",
        "SourceSchema": "employees",
        "SourceTable": "%"
      },
      {
        "Type": "Exclude",
        "SourceSchema": "source101",
        "SourceTable": "dep%"
      },
      {
        "Type": "Exclude",
        "SourceSchema": "source102",
        "SourceTable": "%"
      },
      {
        "Type": "Explicit",
        "SourceSchema": "company",
        "SourceTable": "managers"
      },
      {
        "Type": "Explicit",
        "SourceSchema": "company",
        "SourceTable": "locations"
      }
      ]
  }


Output::
