--
-- Creates a delegation set (a group of four name servers) that can be
-- reused by multiple hosted zones that were created by the same Amazon Web
-- Services account.
--
-- You can also create a reusable delegation set that uses the four name
-- servers that are associated with an existing hosted zone. Specify the
-- hosted zone ID in the @CreateReusableDelegationSet@ request.
--
-- You can\'t associate a reusable delegation set with a private hosted
-- zone.
--
-- For information about using a reusable delegation set to configure white
-- label name servers, see
-- <https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/white-label-name-servers.html Configuring White Label Name Servers>.
--
-- The process for migrating existing hosted zones to use a reusable
-- delegation set is comparable to the process for configuring white label
-- name servers. You need to perform the following steps:
--
-- 1.  Create a reusable delegation set.
--
-- 2.  Recreate hosted zones, and reduce the TTL to 60 seconds or less.
--
-- 3.  Recreate resource record sets in the new hosted zones.
--
-- 4.  Change the registrar\'s name servers to use the name servers for the
--     new hosted zones.
--
-- 5.  Monitor traffic for the website or application.
--
-- 6.  Change TTLs back to their original values.
--
-- If you want to migrate existing hosted zones to use a reusable
-- delegation set, the existing hosted zones can\'t use any of the name
-- servers that are assigned to the reusable delegation set. If one or more
-- hosted zones do use one or more name servers that are assigned to the
-- reusable delegation set, you can do one of the following:
--
-- -   For small numbers of hosted zones—up to a few hundred—it\'s
--     relatively easy to create reusable delegation sets until you get one
--     that has four name servers that don\'t overlap with any of the name
--     servers in your hosted zones.
--
-- -   For larger numbers of hosted zones, the easiest solution is to use
--     more than one reusable delegation set.
--
-- -   For larger numbers of hosted zones, you can also migrate hosted
--     zones that have overlapping name servers to hosted zones that don\'t
--     have overlapping name servers, then migrate the hosted zones again
--     to use the reusable delegation set.
