Hi Jonathan,

Thanks a lot for the PR. I've made a small suggestion for the documentation.

Also, I'm curious, does this work for both local and cloud version of ElasticSearch ? If so we should mention it.

You can use the *remote reindex* API to upgrade directly from Elasticsearch 7 to Elasticsearch 9. This approach runs both clusters in parallel and uses Elasticsearch's remote reindex feature.

This upgrade relies on a script that was specifically built taking jCustomer into consideration. If you are sharing the Elasticsearch instance with other projects, it might need to be adjusted.

Not sure people will know what jCustomer is, maybe we should just say a custom Unomi application instead ?

Hello Serge,
The script is working for both. The user needs at least an Elasticsearch 7 (the source) and an Elasticsearch 9 (the target) to execute the script, no matter where they have been created.
