Upgrading from 0.20.5 to 0.90.0

Elastic Stack Elasticsearch
1

Hi Everyone,

I have a 5 node cluster, with replicas set to 2 with around 70M documents that I would like to upgrade to 0.90.0

I can't seem to find definitive instructions for upgrading, I was thinking something along these lines:

Issue cluster shutdown: curl -XPOST 'http://localhost:9200/_cluster/nodes/_local/_shutdown'
Upgrade each of the nodes using the 0.90.0 deb package
Start elasticsearch on each of the nodes: /etc/init.d/elasticsearch start

Should I look at changing any of these settings prior?

gateway.recover_after_nodes
gateway.recover_after_time
gateway.expected_nodes

Cheers!
