We're in the middle of an upgrade from 0.9.5 to 2.1 and we're doing this: - update all topologies to be compatible with v2.1; throughout the process we're making any changes to both the 0.9.5 and 2.1 versions - deploy Storm v2.1 cluster in parallel to the v0.9.5 one - kill each topology in old cluster and deploy to new cluster - kill old cluster
I know that doesn't directly answer your question, but at least for us we had no expectation that the topologies would remain compatible in a major version update. Good luck!
