This class extends the Search::Elasticsearch client with a \f(CW\*(C`migration\*(C'\fR

Migration APIs <https://www.elastic.co/guide/en/elasticsearch/reference/current/migration-api.html>.

The \f(CW\*(C`deprecations()\*(C'\fR \s-1API\s0 is to be used to retrieve information about different cluster, node,
and index level settings that use deprecated features that will be removed or changed in the
next major version.
