Transfer data from old .kibana index

Hey everyone.
I’m transferring from old ELK 5.6 to OD. Old .kibana contains lots of index templates which has tons of scripted fields. I’ve tried to reindex old .kibana index and then clone it as .kibana_1 index but after starting kibana it says

Another Kibana instance appears to be migrating the index. Waiting for that migration to complete. If no other Kibana instance is attempting migrations, you can get past this message by deleting index .kibana_1 and restarting Kibana.

Any help on this is much appreciated.
