Which raid controller do you have? Most HP SA raid controllers with the BBWC option have this capability.

According to the quickspecs it can do raid level migration.

However because you are converting from Raid0 (no redundancy drives) to Raid1+0 (half of the drives will be used for redundancy), you would need to have at least half of the space unused in Raid0 to be able to convert to Raid1+0. The unused space would be used for mirroring in R1+0.
Also you would have to have an even number of drives in Raid0.
