Hi, You could migrate from Solr to ES without reindexing because at the end of the day it is Lucene that writes data to index. You'd want to make sure your ES mappings match your Solr schema. You'd want to create the matching number of shards and replicas you had in Solr(Cloud?). You'd manually copy Lucene indexes from Solr to ES and pray. I'm sure I'm skipping over about a dozen details you can trip over, though.
