We recently updated Elasticsearch and Kibana from 7.17 to 8.10.2, and noticed that we can't find how to upgrade the system indices from 7 to 8 (like in the 7 to 8 upgrade assistant where we were able to upgrade our indices from 6 to 7).
Are we overlooking something in the UI?
Is a feature planned?
Is there a [straightforward] way of doing this? (How?)
Is there even a good reason for doing this?
Thanks.
