Problem starting kibana 7.2

Hello,

I have just updated kibana to 7.2 from 6.6.1 and when I try to start it I am getting the following error message:

This seam to be elasticsearch problem. I am running a two node cluster and it seam that the 2000 shards/node is not enough since I have lots of indices. I don't see how can I lower the number of shards to fit in those 2000. Any idea?

@zozo6015 I think you might have better luck with this one in the Elasticsearch forum thx

Closed all of the old indices which were not updated and that cleaned up enough shards so that I could start kibana.
