Converting from RAID 0 to Raid 1 on DL460G6

Converting from RAID 0 to Raid 1 on DL460G6

When the server was originally set up, the RAID level was set to 0 on disk 0 only. The second disk did not get configured. When we found the problem, the server was configured and running in the domain. We want to add the second drive to the array (2 drives are identical) and change it to RAID 0+1. Can this be done without nuking, recreating RAID, and restoring? All of the advice I have found is split between yes you can and no you can't. Any help is appreciated.

If the second disk is the same size or bigger, AND the HP Smart Array P410i has the battery-backed write cache (BBWC), then YES.

Available upgrades: 256MB, Battery kit upgrade (for BBWC), or 512MB with BBWC, and Smart Array Advanced Pack (SAAP-RAID 6 and 6+0)

Addition of the battery backed cache upgrade enables array expansion, logical drive extension, RAID migration, and stripe size migration

@vcespon : you wrote "yes"... could you please explain the steps. I'm using P410i and see no possibility to convert RAID0 to RAID1...
