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

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.
