本节讨论在将应用程序从一个版本的Elasticsearch迁移到另一个版本时需要注意的更改。

作为基本规则：

*   次要版本之间的迁移 - 例如 5.x到5.y - 可以通过 [一次升级一个节点](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/rolling-upgrades.html) 来执行。
*   连续版本之间的迁移 - 例如 2.x到5.x - 需要[完全群集重新启动](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/restart-upgrade.html)。
*   非连续版本之间的迁移 - 例如 1.x到5.x - 不支持。

有关详细信息，请参阅[升级Elasticsearch](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/setup-upgrade.html)。
