Michael McCandless	399f0ccce9	Core: add only_ancient_segments to upgrade API, so only segments with an old Lucene version are upgraded ... This option defaults to false, because it is also important to upgrade the "merely old" segments since many Lucene improvements happen within minor releases. But you can pass true to do the minimal work necessary to upgrade to the next major Elasticsearch release. The HTTP GET upgrade request now also breaks out how many bytes of ancient segments need upgrading.
