Kibana dashboards export/import not working

We have 2 different Elasticsearch clusters (A-cluster & B-cluster) - The incoming data stream is pretty similar in both clusters. But the index naming differs in both clusters.

I'm having trouble export the dashboards from A-cluster to B-cluster. I could import find, but it says data is missing, when I try to view the dashboard in B-cluster. I have also manually changed the index-ID's to match the B-cluster indices.

Any help is appreciated.

this is kind of a wild guess, but when you exported your Dashboard did you remember to export the associated Visualizations and Searches? See this related question: How to save dashboard as json file what versions are yoiu trying this on ? what errors exactly and screenshots/logs would help.

Thanks
