You can revert without assistance when reverting new or test systems, but you should call technical support if you encounter problems during or after upgrading, or if you want to revert a production system.
You can revert to an earlier release family without assistance from technical support only in the following scenarios:
- You upgraded to a new release on a test system and you want to return to the original release when testing is completed.
- You are configuring a new storage system—running a later release of Data ONTAP and not yet in production—in an environment in which you have standardized on an earlier Data ONTAP release.
Do not attempt to revert Data ONTAP in a production environment without assistance. If you encounter any of the following circumstances, contact technical support immediately:
- The upgrade process fails and cannot finish.
- The upgrade process finishes, but the system is unusable in a production environment.
- The upgrade process finishes and the system goes into production, but you are not satisfied with its behavior.
