Removing node in ElasticSearch where cluster awareness is enabled

I have a ES cluster created with Cluster allocation awareness enabled with 4 zones and each zone has 2 masters and 3 data nodes. I have primary shards on those zone nodes. Currently I got a requirement to remove 1 zone completely. What is the procedure to remove 1 zone completely.

What is the solution for this problem? Any help would be highly appreciated.

Do you have replicas set to cover all zones?

Yes each index has 5 shards and 3 replicas .

Ok, well you could drop a replica and then remove one zone. That should do it.

Thanks a lot. It's worked .
