Upgrade to 7.2

[mathurin68]

My upgrade of my elkstack 6.8 to 7.2 seems to have gone OK(cluster is green) except for the following kibana error -

money@elkstack:/etc/kibana$ sudo systemctl status kibana.service

I'm not sure what else try...

is there something in your config?
I upgraded to 7.2 on my test cluster and it worked without any problem.

Hah yeah I knew it was something stupid I was doing...
In my kibana.yml I had
elasticsearch.url:
and when I upgraded from 6.6 to 6.8 the cluster still worked
but when I upgraded all the way to 7.2
I had to change it in kibana.yml to
elasticsearch.hosts:

... and everything seems to be starting now.

Thank you!!
