After CEP-21 would it be possible to take a cluster of 6 nodes, spin up 6 new nodes to duplicate the 6 existing nodes and then spin down the original 6 nodes. Basically, I am thinking of the case where a cluster is running version x.y.z and want to run x.y.z+1, can they spin up an equal number of x.y.z+1 systems and replace the old ones without shutting down the cluster?
We currently try something like this where we spin up 1 system and then drop 1 system until all the old nodes are replaced. This process frequently runs into streaming failures while bootstrapping. Any insights would be appreciated. Claude
