I do not know java, so I do not know how to use the following tools. > **[dadoonet/elasticsearch-beyonder](https://github.com/dadoonet/elasticsearch-beyonder)** > > elasticsearch-beyonder - Elasticsearch Beyonder project gives some features beyond elasticsearch itself. Therefore, we are trying to make use of the following tools.(like RDBMS migration tool) · Prepare the changed mapping file and put the version name in the file name · Using reindex and alias, after creating a new schema, import data from the old schema Does such a migration tool exist in the world? Is there another way to do it? ---

Beyonder does not perform any migration. It's "just" a tool that creates missing indices by looking at what you have in your classpath as settings definitions. Not related to migration. ---
