that was a big jump. from 5.4.0 to 6.6.1

in past when I had a problem I remove .kibana_1 indice and it worked. (but I did upgrade from 6.x to 6.y)

I do not know if that will solve your problem or not.

I need my .kibana index to be reindexed and working in 6.6.1,
btw i'm passing through 5.6.0 as intermediate upgrade.

Hi,
