Upgrading cluster and its monitoring cluster

Hi there,

When I set up my separate monitoring cluster for my production cluster, I did it in the same version 8.8.2 as the production one.

Now I want to upgrade the production cluster version to 8.12.

How should I proceed with the version upgrades, production cluster first and then the monitoring one, or the other way around ?

Any of the 2 is the same ? ( new version cluster sending logs & metrics to old version cluster VS old version sending to new version )

Thanks in advance.

Hi,

When upgrading Elasticsearch clusters, it's generally recommended to upgrade the monitoring cluster before the production cluster. This is because newer versions of Elasticsearch are typically able to understand data sent from older versions, but the reverse is not always true.

Regards

Thanks @yago82 !
