JBOD over multiple disks

If one day, I decided to change to RAID 1, can I switch Flex-RAID (JBOD) to X-RAID (RAID-1)?
All data in that second volume are not required anymore or have been backup, I suppose I just need to do the following step:

1. Copy all data out from second volume
2. Remove second volume physically
3. Configure re-enable X-RAID (JBOD) for the first volume
4. Add a new disk (size > volume 1)
5. Select add parity
6. Done - now X-RAID - RAID 1 on both 2TB drive

please correct if i'm wrong

In the OS 6 manual it mention like this, so I suppose for JBOD with only one volume, it okay to switch to X-RAID mode again.

Change from Flex-RAID to X-RAID2 If your system contains only one volume, you can easily switch from Flex-RAID to X-RAID2. Data on the Flex-RAID volume is preserved when you switch to X-RAID2. If your system contains multiple volumes, you must first reconfigure your disks into a single volume. Note: When you switch to X-RAID2 mode, any extra disks installed in your system are automatically reformatted and used for storage expansion. You cannot change the RAID mode of a RAID 0 or RAID 10 volume.
