I don't believe we explicitly tested the timelion plugin so it very well may be that permissions don't exist to allow user's to see any index used to store timeline information.  We only generate permissions for the indices: .operations, .orphaned, .kibana.<userhash>, project.<namespace>.<projectuid>.<date>

Is it possible for you to identify what query is being executed against which index?

I'm not certain where this solution originated but it explicitly says 'Export any custom index-patterns, visualizations, dashboards' which addresses the loss of visualization.  The solution does not, however, describe how to import them back to the index which could be accomplished with a curl statement or likely Kibana has and import function.

Looks like it might be possible to import dashboards in Kibana5 -> https://www.elastic.co/guide/en/kibana/5.0/loading-a-saved-dashboard.html

I'll try it out and report back here

Ok, exporting / importing appears to work. Management -> Kibana -> Saved Objects -> Export Everything / Import. Works even once I delete my kibana index, refresh, import. I'll update customer as well.

This is not a bug.  User's are only allowed to perform actions against indices for which you have permissions.  If you are a cluster-admin then you can see all the data in the ES cluster.  If you are a non-admin, you can only view data against the indices which are a 1:1 match to the Openshift namespaces you can access.  I stood up a 3.11 cluster and loaded Timelion in Kibana.  The initial load provides a text box that is trying to do something against all indices:

.es(*)

This is reporting correctly for non-admin users.  If I modify it as advised in the ES documentation [1] to my test project:

.es(index=project.myproject.5c466a17-8961-11e9-b2db-525400b6beac.*)   which is in the form of project.<namespace>.<namespace_uuid>.<date> 

the result is a graph of the data available.

Following up based on the following information from the client:

* Kibana users before upgrade are unable to see their visualizations after upgrade without deleting their kibana index

I am unable to reproduce by:

* Installing latest 3.10 with kibana index mode unique
* Log in as a cluster admin and create queries, visualizations, and dashboards
* Upgrade the cluster to latest 3.11
* Log in as a cluster admin and load  queries, visualizations, and dashboards

Note there are no failures. This makes me think we are running into [1] which is related to load, specifically the number of projects associated with a particular user.  User's with a large number of projects prior to [1] can run into timeout conditions where seeding is not complete and subsequently users would see a permissions denied issue.

There is nothing in the code or the way Kibana loads these assets that should require deleting the Kibana index; I'm not certain from where that advise originated.  Per the discussion with the customer, we will provide a script, as a work around that seems to mitigate the issue, to export and import a user's assets from their kibana index.
