Hi Jeff, I was under the impression that streaming in a cluster with mixed binary versions might be problematic, but as long as the cluster is on the same binary version (e.g. after a rolling upgrade), we still can have SStables in mixed data formats and streaming will work?

You won't notice any issues (all versions of cassandra are backwards compatible at least 1 version), and sstables will be slowly migrated to the new format as you compact, but you should still run it (upgradesstables) explicitly because when it comes time to run repair/boostrap/decommission/etc, you'll need all sstables on the same/current format.
