Hi, We have setup a environment with 5 nodes(3 VM & 2 Cloud) with multiple index in Elastic Search version 0.90.13. 5 Shard with 3 replica Seven .Net Applications using Nest wrapper pushing data to the Elastic Source to Index periodically everyday. Now we are planning to migrate our environment from 0.90.13 to 1.7 Elastic Search. Here I request Experts suggestion and steps to consider to achieve this. Thanks, S.Kannan ---

You cannot run ES 1.7 with Java 6, only 7. ---

Ok, let me check that again and come back. is there is any command to get it from Marvel Sense ? Also please let me know one more information regarding migration. As mentioned we have ES 0.90.13 in 5 nodes and planning to add additional nodes now (before migration from 0.90.13 to 1.7) so in that case what Java version we need to install in the new nodes, Java 7 or the latest version? ---

To get what from Sense? The best information you can get is in the docs as I linked to before. Regarding Java, we recommend 8u40 and above. ---

Run `java -version` on the CLI, or `curl "0:9200/_cat/nodes?h=n,j&v"`. ---

Thanks 🙂 , also please let me know one thing, presently we are having ES 0.90.13, if we add new nodes to our cluster, then the shards will be automatically shared across the new nodes ? ---

Yes, but you cannot do a mixed 0.90.X and 1.X cluster. ---
