Elasticsearch can usually be upgraded using a rolling upgrade process, resulting in no interruption of service. This section details how to perform both rolling upgrades and upgrades with full cluster restarts.
To determine whether a rolling upgrade is supported for your release, please consult this table:
|Upgrade From||Upgrade To||Supported Upgrade Type|
Rolling upgrade (where `y > x `)
Take plugins into consideration as well when upgrading. Most plugins will have to be upgraded alongside Elasticsearch, although some plugins accessed primarily through the browser (
_site plugins) may continue to work given that API changes are compatible.
