      Description

      Upgrade from Elasticsearch 5.6.3 to 6.3.0 which also means Lucene upgrade from 6.6.1 to 7.3.1.

      Elasticsearch 5.6 is a migration version, the intermediate step between 2.x and 6.x,
      when moving to 6.x things get stricter:

      • no more elasticsearch doc type
      • boolean term query must be true or false (and not 0 or 1)
      • the embedded mode is even more discouraged by requiring plugin not released by elasticsearch
      • alias cannot be deleted, you have to delete index instead
      • the default number of shard in 6.3 is 1, for now Nuxeo keep the 5 shards configuration

      Note that queries generated by 6.3.0 are not backward compatible with 5.6 so cluster must be 6.x
