name : update-alias.rst **To associate an alias with a different KMS key** The following ``update-alias`` example associates the alias ``alias/test-key`` with a different KMS key. * The ``--alias-name`` parameter specifies the alias. The alias name value must begin with ``alias/``. * The ``--target-key-id`` parameter specifies the KMS key to associate with the alias. You don't need to specify the current KMS key for the alias. :: aws kms update-alias \ --alias-name alias/test-key \ --target-key-id 1234abcd-12ab-34cd-56ef-1234567890ab This command produces no output. To find the alias, use the ``list-aliases`` command.
