Elasticsearch upgrade without service interruption?

Elastic Stack Elasticsearch
1

If I have an elasticsearch installation at, say, version 0.90.3, and I want
to later upgrade to 0.90.2 or 0.91 or even 1.0, can that be done one node
at a time? So I can keep the cluster available during the upgrade?

Hey,

major version upgrades (as from 0.90 to 1.0) require a cluster restart.
Minor versions can be done in a rolling upgrade, one node at a time.
You might want to disable shard allocation during that. See
