How to do a rolling downgrade of servers

Elastic Stack Elasticsearch
1

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

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