after updating kibana I am missing a few (that is not all, but some) of the dashboards and index-patters that have been there prior to the update. Some more background:
We have a multinode elasticsearch-cluster including two kibana-instances behind a loadbalancer. We postponed the update of elasticsearch and kibana v7.9.1 to v8.x as long as we could (more than a year now), after it broke some things in our test-cluster. Today was the day we wanted to update the productive cluster.
First surprise: elasticsearch was already updated to 7.17.3 while kibana was still on 7.9.1. Nevertheless we updated kibana to 7.17.3 without any problems (at first sight).
Now we see, that some dashboards as well as index-patterns are missing after the update of kibana. I can find the dashboards in some very old indizes with names like ".kibana_4". But they cannot be found in the .kibana_7.17.3_0001 (which .kibana also points to).
This cluster is very old, I guess it has been around already when kibana was at version 3. For sure I know that kibana/elasticsearch 6.x was still in use when I started at this company.
Is there a way to extract the dashboards from the indices to recover them (I think I will recreaty the index-patterns manually instead of recover them somehow)?
Alternatively: We have a snapshot of all .kibana* indices before we have done the update, how would I use that snapshot to recover the dashboards now that we are on v7.17.3?
