I am migrating ElasticSearch cluster 7.2.0 to 7.6.2. The latter was deployed by ECK. Data and mapping don't really seem to have any conflicts. Now, there are two questions w.r.t users that I wanted to ask.
- Is there any built-in feature to migrate the users from the old cluster to the newer one ?
- With the cluster running image 7.6.2, I am not able to list any users via the api: /_security/users
so there is no way I am able to know if the migration did happen !
Any help will be appreciated !
