How to upgrading Elasticsearch To A Newer Version

The key is exporting the instance.
Disable shard movement

curl -XPUT http://elk2.domain.com:9200/_cluster/settings -d '
{
  "transient": {
    "cluster.routing.allocation.enable": "none"
  }
}'

Migrate to new version (on linux)

export INS=1
alias cp=cp
cd /opt
/opt/elasticsearch-ins${INS}/bin/start_elastic.sh stop
unzip -qq /var/tmp/elasticsearch-2.3.0.zip
mv elasticsearch-ins${INS} elasticsearch-ins${INS}-2.2
mv elasticsearch-2.3.0 elasticsearch-ins$INS
cd elasticsearch-ins${INS}
cp -rp ../elasticsearch-ins${INS}-2.2/current .
cp -rp ../elasticsearch-ins${INS}-2.2/config/elasticsearch.yml config/.
cp -rp ../elasticsearch-ins${INS}-2.2/bin/start_elastic.sh bin/.
chown -R elastic:elastic /opt/elasticsearch-ins${INS}
/opt/elasticsearch-ins${INS}/bin/start_elastic.sh start

Migrate to new version (on solaris)

export INS=1

cd /opt
svcadm disable -s d${INS}/elasticsearch
unzip -qq /var/tmp/elasticsearch-2.3.0.zip
mv elasticsearch-d${INS} elasticsearch-d${INS}-2.2
mv elasticsearch-2.3.0 elasticsearch-d$INS
cd elasticsearch-d${INS}
cp -rp ../elasticsearch-d${INS}-2.2/current .
cp -rp ../elasticsearch-d${INS}-2.2/config/elasticsearch.yml config/.
chown -R elastic:elastic /opt/elasticsearch-d${INS}
svcadm enable -s d${INS}/elasticsearch

Re-enable shared movement, once the cluster is back up

curl -XPUT http://elk2.domain.com:9200/_cluster/settings -d '
{
  "transient": {
    "cluster.routing.allocation.enable": "all"
  }
}'
