Manual copy of indexes

Hi All,

I want to copy indexes created by embedded elastic search and copy that data into a live elastic search and use it. So these are the steps I followed.

  1. Generated indices using Node Client (like embedded elastic search) with a index name testindex

  2. After that I had a live elastic search cluster with one node and I created an empty index by the same name testindex and the same mappings as used to generate indices using NodeClient.

  3. After that I closed testindex and copied the index data from the embedded elasticsearch to the data directory for testindex in elastic search

  4. Opened the index testindex. After opening the index the copied data is deleted.

Any ideas why that could have happend. If I want to reused the indices generated by embedded elasticsearch by copying them to the data folder in elastic search, what all files should I copy.

Please advise
