Can I Upgrade an SFS Turbo File System from Standard to Standard-Enhanced?

No. The type of an existing SFS Turbo file system cannot be changed.

If you want an SFS Turbo file system of another type, delete or unsubscribe from the current file system and purchase a new one with your desired type. If you still need the data in your old file system, purchase a new file system and migrate data to the new file system. After the data is migrated, delete or unsubscribe from the old file system.
