Thank you all for the suggestions.
I am not trying to scale up the cluster for capacity but for the upgrade
process instead of in place upgrade I am planning to add nodes with 3.11.6 and
then decommiss

that I can reason what
should happen. I would either scale up or upgrade (depending on which is more
urgent), then do the other.

Technically you can. You'll be able to add 3.11.6 nodes to a 3.11.3
cluster. In fact, the reverse works too in my tests but I personally
wouldn't want to do it in production.

Rightly said by Surbhi, it is not good to scale with mixed versions as
debugging issues will be very difficult.
Better to upgrade first and then scale.

In case of any issue, it gets very difficult to debug when we have multiple

Hi, I would say „It depends“ - as it always does. I have had a 21 Node Cluster
running in Production in one DC with versions ranging from 3.11.1 to 3.11.6
without having had any single issue for over a year. I just upgraded all nodes
to 3.11.6 for the sake of consistency.

We also had to expand the cluster and we also discussed about expansion
first and than upgrade. But finally we upgraded and than expanded.
As per our experience what I could tell you is, it is
