The sstableupgrade tool

Upgrade the SSTables in the specified table (or snapshot) to match the current version of Cassandra.

If restoring with sstableloader, you must upgrade your snapshots before restoring for any snapshot taken in a major version older than the major version that Cassandra is currently running.
