What happens when a volume's tiering policy is changed from "snapshot-only" to "auto"?

Changing a volume's tiering policy from "snapshot-only" to "auto" implies a change in how data is managed and moved across tiers of storage. When a volume's tiering policy is set to "auto," the system dynamically manages data placement based on usage patterns, which can optimize performance and cost.

The correct answer highlights that this specific tiering policy change is permissible and does not come with constraints like the requirement for a perpetual license, which would suggest that additional fees or licensing issues are involved. Additionally, it does not imply that resetting the service connector is necessary for the change to take effect, as this action is not standard protocol when adjusting tiering policies.

Understanding that only subsequent tiering behavior will change reflects the fact that existing data already governed by the "snapshot-only" policy will remain unchanged until the system applies the new auto-tiering behavior moving forward.

Thus, it's evident that the chosen response properly aligns with the operational dynamics of tiering policies in cloud services, indicating that such a change is valid and enforceable without additional complications.
