Updating Apache Druid across a cluster of many nodes

Apache Druid Q&A Core
#1

I have many nodes in my production cluster of Apache Druid.
All versions are 0.20.1.
If I update the cluster, node by node, to the latest version, will it be OK during the update?
Because it takes time updating each node. And I want to node, during the process of updating, is that OK for other nodes that are behind in version? Until they get updated too.

I know it MUST be ȮK, as the updating is not major but is MINOR. But still, I thought asking community might give more insight

Now, my question is that, is it possible for me

Relates to Apache Druid 0.20.1
