Yes, this is possible using the HP Array Configuration Utility. The term you're interested in is "Array Transformation". See page #16 of the manual.
- Add the physical drives.
- Expand the array.
- At that point, you'll either want to add a new logical drive or expand the existing.
- If you expand the existing, you may require downtime since it's your C: drive.
HP even has a video detailing this..

You don't mention which specific SmartArray controller you have but on all recent models online-RAID-migration is possible and safe, but slow.
