I have been working in upgrading my ES 1.x to 2.x recently. I have upgraded my codes from 1.x JAVA API to 2.x JAVA API. Now I am migrating my data from ES 1.x cluster to 2.x cluster.
For this purpose I have few solutions, make the mapping for ES 1.x compatible with 2.x and then move data to cluster with ES 2.x.
But I want to do is, use BulkProcessor API so that I can index selective data from ES 1.x to ES 2.x.
How can I do this ?
