The SSTables in this snapshot '<tag>' are not compatible 

Instructions to upgrade the OpsCenter snapshot.

If you receive an error message that includes "The SSTables in this snapshot '<tag>' are not compatible with the current version of Cassandra", it means you must upgrade your snapshot to the current major version of DataStax Enterprise.

How to
  1. Log in to each node.
  2. Run the sstableupgrade script for every keyspace and table you need to restore; passing it the keyspace, table, and OpsCenter snapshot tag received from the error message.

    How you run the script depends on how you installed DataStax Enterprise.

  3. Retry the restore from OpsCenter.
