I have two elasticsearch servers running on two machines which have X and Y no of indexes respectively. I need to join both of them, so that my new machine has X+Y no of index without any loss of data. Will merging the data/ folder from both the instances do the trick? -- ---

I would create an Alias and play with replication/allocation to put all in 1 node... then you will still have 2 indices but all of your data will still be under 1 name on 1 node.
