Hell team -
I'm in a situation where i need to upgrade ES1.x to ES6.2,
I have installed ES6.2 nodes equal no of number as OLD ES cluster ( 3 Data nodes and 3 Master nodes)
1.How can i include the reindex.remote.whitelist in the new ES nodes which should include the all the 3 data and 3 master.
2.should i include this setting variable in all the master and data nodes in the new cluster?
3.. How can i provide the shard and replica settings to entire ES cluster.
