**To update an accelerator**

The following ``update-accelerator`` example modifies an accelerator to change the accelerator name. You must specify the ``US-West-2 (Oregon)`` Region to create or update accelerators. ::

    aws globalaccelerator update-accelerator \
        --accelerator-arn arn:aws:globalaccelerator::123456789012:accelerator/1234abcd-abcd-1234-abcd-1234abcdefgh \
        --name ExampleAcceleratorNew \
        --region us-west-2

Output::

    {
        "Accelerator": {
            "AcceleratorArn": "arn:aws:globalaccelerator::123456789012:accelerator/1234abcd-abcd-1234-abcd-1234abcdefgh",
            "IpAddressType": "IPV4",
            "Name": "ExampleAcceleratorNew",
            "Enabled": true,

            "IpSets": [

                        "198.51.100.52"
                    ],
                    "IpFamily": "IPv4"
                }
            ],
            "DnsName":"a1234567890abcdef.awsglobalaccelerator.com",

        }
    }
