+GENERAL UPGRADING ADVICE FOR ANY VERSION
+========================================
+
+Snapshotting is fast (especially if you have JNA installed) and takes
+effectively zero disk space until you start compacting the live data
+files again. Thus, best practice is to ALWAYS snapshot before any
+upgrade, just in case you need to roll back to the previous version.
+(Cassandra version X + 1 will always be able to read data files created
+by version X, but the inverse is not necessarily the case.)
