Rollback Cassandra after 1 node upgrade
Hi We have been forced into rolling back our Cassandra after 1 node upgrade. The node was upgraded 10 days ago. We have the backup of the old data. Strategy one which we are thinking : 1. Rollback to old binaries and configuration. 2. Restore the old data from backup. 3. Run Repair. Another Strategy is to bootstrap the node as new after changing the binaries. Which of the strategies is best? Regards Manish
