**To update an accelerator** The following ``update-accelerator`` example modifies an accelerator to change the accelerator name to ``ExampleAcceleratorNew``. 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 Output:: { "Accelerator": { "AcceleratorArn": "arn:aws:globalaccelerator::123456789012:accelerator/1234abcd-abcd-1234-abcd-1234abcdefgh", "IpAddressType": "IPV4", "Name": "ExampleAcceleratorNew", "Enabled": true, "Status": "IN_PROGRESS", "IpSets": [ { "IpAddresses": [ "192.0.2.250", "198.51.100.52" ], "IpFamily": "IPv4" } ], "DnsName":"a1234567890abcdef.awsglobalaccelerator.com", "CreatedTime": 1232394847, "LastModifiedTime": 1232395654 } } For more information, see `Accelerators in AWS Global Accelerator <https://docs.aws.amazon.com/global-accelerator/latest/dg/about-accelerators.html>`__ in the *AWS Global Accelerator Developer Guide*.
