Phase 7: Clean up after upgrade or rollback
You may only begin this phase if:
This phase contains steps to remove the rollback configurations and data you created at the beginning of the upgrade process prior to upgrading the cluster to the new version of Cassandra. It also contains the steps to restore the support services you disabled before the upgrade.
Remove the configuration backups you created in Back up Cassandra configuration files.
Remove the snapshots you created in Create a pre-upgrade snapshot backup. For example:
nodetool clearsnapshot -t pre-upgrade
Requested clearing snapshot(s) for [all keyspaces] with snapshot name [pre-upgrade]
Re-enable any automated repair schedules you disabled in Disable automated node repairs.
Re-enable any automated backup schedules you disabled in Disable automated backups.
At the end of this phase:
All backup files generated in preparation for the upgrade have been deleted.
All scheduled repair and backup operations have been restored.
