We already have SOLR instance and we would like to migrate indexes that were already created into our ES instance. I see that river plug in was available, but was deprecated since then. Also, I would rather avoid to do it "manually" via to connect to solr and then bulk ingest into ES... any other automated options out there?

Hi @krinker,

I do not see many other options except the one you mention. There is a tool called [solr-to-es](https://github.com/o19s/solr-to-es) which basically reads data from Solr and bulk-indexes it into Elasticsearch. You'd still need / should create indices with proper mappings beforehand. Upon a quick glance, the source code seems rather simple and straightforward but I did not use it so far.
