Jeremy Hanna commented on CASSANDRA-5646:
-----------------------------------------
It's generally recommended to run nodetool upgradesstables between any two
major versions prior to doing any kind of streaming operation like move,
bootstrap, or repair. That will avoid any mixed version sstable issues. I'm
not sure what the guarantees are. I believe each node can read the prior major
version files, but sometimes the streaming operations have issues.
