Hi, I have 3 ES servers that are m1.large. I need to change the machines types and reduce to 1 node. The indexing and the shards were left at there default values and I am using unicast. So if I want to go to one node can I just stop 2 ES severs? And on the last reaming node, that is e.g. m1.large, can just add another 1.medium node then when done syncing then stop the first m1.large? I should have 1 m1.medium then Thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

This should work as described. Make sure that you have enough disk space to hold all your primary shards.
