The migration operation is idempotent and re-entrant. If the migration operation fails, you can fix the error and retry the migration using the failed CLI command. If you press ctrl+c or cancel the migration accidentally, retry the migration operation with the same CLI command. When you retry the migration, tool tries to use the new appliance (if already deployed) and performs migration operation on such appliance. In case the issue persists, you can redeploy (delete and deploy new one) appliance by setting forceDeploy field value to True for in the input.json and retry the same CLI command.
