Unless you strictly opted out of Raft in the configuration, Raft will be enabled as you upgrade. All you need to check is whether it completed successfully.

Not sure WDYM on the last statement for CQL. Are you saying you upgraded and the nodes wouldn’t get start CQL until you finalized the entire upgrade? That shouldn’t happen.

I double checked my logs and the way I was streaming them, it was coming from all pods and it caused some confusion. Thanks for your help, @Felipe\_Leme\_Gasparini!

I have followed the instructions from here i.e. applied changes to scylla.yaml before restart and then restarted the nodes.

What am I missing?
