@tiagocosta I did not attempt any migration process, this environment is fully spinned up from:
When doing curl localhost:9200/_cat/indices?v , does it should show .kibana and .kibana_N indices? I thought .kibana migrated to .kibana_N after 6.5.0 version. It is weird though that .kibana_1 does not show any aliases but, when I try to restore it, It says duplicates were found [.kibana (alias of [.kibana_1 ...]')
