Fleet Integration Assets Fail After Upgrade to 8.9.0

[tomx1]

I've just upgraded our Cluster from 8.8.0 to 8.9.0 and now all the dashboards and visualizations shipping with fleet integrations are no longer working. If I try to re-install the fleet integration it fails and in the Kibana log I see:

[2023-08-22T12:31:27.678+00:00][WARN ][plugins.fleet] Failure to install package [netflow]: [Error: Non-unique import objects detected: [dashboard:netflow-14387a13-53bc-43a4-b9cd-63977aa8d87c,dashboard:netflow-34e26884-161a-4448-9556-43b5bf2f62a2,dashboard:netflow-38012abe-c611-4124-8497-381fcd85acc8,dashboard:netflow-77326664-23be-4bf1-a126-6d7e60cfc024,dashboard:netflow-94972700-de4a-4272-9143-2fa8d4981365,dashboard:netflow-acd7a630-0c71-4840-bc9e-4a3801374a32,dashboard:netflow-c64665f9-d222-421e-90b0-c7310d944b8a,dashboard:netflow-feebb4e6-b13e-4e4e-b9fc-d3a178276425,search:netflow-a34c6611-79d8-4b50-ae3f-8b328d28e24a]]

Even a complete reinstall does not help, I don't know where those dashboards and searches Kibana is complaining about are hiding. To me all those dashboards and visualisations shipping with fleet integrations are really a hassle, they are constantly losing views and have to be re-installed regulary.
I assume they have not been well tested in conjunction with several spaces (which we are using).

However, has anybody a hint where to take a look to solve this issue?

Update: If I do a search for those dashboard IDs I find them in the .kibana_ingest_8.8.0_001 Index. I think something went wrong during updating aliases / indices to current Kibana version during upgrade from 8.8.0 to 8.9.0.

I currently have the following kibana aliases (which is really a mess) but to me it looks like the ".kibana" alias should point to 8.9.0 index (which is missing) and not to .kibana_8.8.0_001? But I'm not sure if things get completely broken if I just re-configure the alias so it points to the correct index version

alias                           index                                 filter routing.index routing.search is_write_index

Just to clarification: I can't see those dashboards in the Kibana Webgui anymore.

Upgrading from 8.9.0 to 8.9.1 magically fixed the problem
