Breaking changes
editThis section discusses the changes that you need to be aware of when migrating your application from one version of Elasticsearch to another.
As a general rule:
-
Migration between minor versions — e.g.
6.xto6.y— can be performed by upgrading one node at a time. -
Migration between consecutive major versions — e.g.
5.xto6.x— requires a full cluster restart. -
Migration between non-consecutive major versions — e.g.
2.xto6.x— is not supported.
For more information, see Upgrade Elasticsearch.
