I'm having a little bit of a hard time understanding how to upgrade my eck operator and elastic stack version.
Currently I'm on eck 1.0.0-beta1 which is compatible with the latest operator as per this guide Upgrade ECK | Elastic Cloud on Kubernetes [1.9] | Elastic
I want to upgrade both my eck operator to the latest and my Elasticsearch version from 7.4.0 to 7.10.2 and afterwards maybe to another version.
As far as I understood from the documentation, in order to upgrade to eck 1.9.1, there is nothing in particular I must do except replacing current CRDs as they were changed in v 1.7.0 and then re-creating them. Everything else should be smooth.
I don't have the initial manifests/deployments with which I've created the stack so my only option is to directly edit Elasticsearch.
Is it safe to edit Elasticsearch with kubectl edit Elasticsearch and then replacing the version of elastic stack (e.g.: Version: 7.4.0 with Version: 7.10.2) with whichever version I want? Below is my current Elasticsearch config, as seen when issuing kubectl describe Elasticsearch.

Also, what's the order in which I must make the upgrade, first the operator then elastic stack version or first elastic stack version and then the operator?
Any help is greatly appreciated!
