We want to upgrade from Elasticsearch 1.7 + Kibana 4.1 to Elasticsearch 6.4 + Kibana 6.4.
We have setup a new cluster using Elasticsearch 6.4 + Kibana 6.4. We also migrated the Elasticsearch index using reindex-from-remote approach successfully.
Since there are so many Kibana visualizations created in the old cluster, we want to migrate them to the new cluster without re-creating.
I have followed this document to reindex .kibana index. When opening the saved visualization, I got error "The index pattern associated with this object no longer exists."
Then I found this thread and tried the workaround with Export/Import:
While importing I still receive this warning: " The following saved objects use index patterns that do not exist. Please select the index patterns you'd like re-associated with them. You can create a new index pattern if necessary." along with this error message: "Cannot read property 'save' of undefined".
Is this the right way to migrate visualizations from ver 4.1 to 6.4?
